You Don't Have to Take Our Word for It!

Here's what some of our satisfied customers have to say about KPS Princeton Garage:


Had a problem with my car , took it to kps it was diagnosed as a loose heat shield, they saved me quite a bit of money with their honesty .I recommend them very highly. You can also tell they do a very good job, because on any given day you can drive past the place and see alot of different foreign cars , waiting to get serviced.


Took my classic car to KPS, the best car repair experience! They kept me very well informed and did quality work! The car runs excellent ( pure American muscle)! Kudos to Mark and the crew!


Every interaction has been perfect. My old car drives perfectly. Numerous repairs (all appropriate in light of the age of the vehicle) and routine maintenance all perfect experience with these folks.


Happy to give them my business. Mark and Bob very knowledgeable, nice/friendly, and act quick. I called them about my issues for my Range Rover and within 30 minutes they sent a quote. Repairs took few days longer than expected but that was due to waiting on parts. I Have full faith in these guys to work on European/German vehicles. Honest hard working guys who won't rip you off like the dealers. & the complimentary full car wash is a nice added touch! Happy I found KPS




Have been going to KPS for a while now they are all so helpful! Pricing is very reasonable... go over and above to take care of anything I asked for my car is 13 years old and it needs TLC and I never feel I'm getting overcharged and more importantly my car still runs like a dream! Thank you to Mark and Bob in the entire team...


Always very good service! Everyone is friendly and very respectful and always willing to help


Love KPS! They are friendly and honest and they stand behind their work. We have been going to them for years and are very happy with their service!!


My apologies for a long review.... but hopefully it will help other folks... 2019 Porsche Cayenne, just coming off of warranty 40,000 miles coverage, so I was looking for a permanent shop (no longer going to dealership and giving my left arm and right leg for maint services).... I needed to change all four tires (just mount and install, tires bought on-line). Also change all four brakes and rotors.... First shop, surprisingly didn't charge me a diagnostic fee but told me that front driver side strut is leaking (cost to replace is $3,300). Brakes and Rotors ($1,500) and they don't do tires... all the cost before taxes and fees... So obviously I needed to get second opinion... Second shop, charged me $240 for diagnostic and gave me a quote $3,500 for a brake and rotors and based on diagnostic report (very good one with videos and color pictures), NO issues with front driver side strut... Crazy, I'm not paying $3,500 for a brake and rotor job even if it is Porsche... Third shop, quoted me a $1,800 for brakes and rotors. Odd that over 100 reviews but ALL 5 stars and the shop (website) doesn't any info on licensed mechanic credential... seem odd... LASTLY, fourth shop was KPS PG. Quote was $2,100 for a brake and rotors... $280 for mounting n balancing all 4 tires...$140 for wheel alignment.... Interacted with Mark and Bob (both) seem honest and straight forward.... complimentary wash "detail" was a very pleasant surprise (much better than dealership). I don't have negative things to say... very much a local shop. I will definitely be coming back for my 50k maint svc....


Excellent service - great communications, cars are ready when promised. Our cars are older (8, 12, and 21 years old) and I feel confident that we will drive them for many more years.


Prompt service. Very professional guys. Would certainly recommend for your service Needs!


I had a battery installed. In and out in 30-minutes. Very fast and courteous service.


They have always done a great job of maintaining my Honda Accord.


Excellent service. My wife had her Calipers and Rotors done last year and I had my Starter done recently. Everyone is very knowledgeable and they have the best prices in the area. 10/10 would recommend KPS to anyone in need of vehicle maintenance.


They fixed my company truck in good time and were extremely fair on the price.


These guys are just excellent. If you need a car repair shop for European brands that you can trust, KPS Princeton Garage is the right place to go through. The guys are reliable, and the quoted amount always matches the invoice amount, they always give me a call if they found something new. I serviced, and Audi A8, and Mercedes S class, Mercedes R wagon, no issues whatsoever. They usually can get parts next business day or the day after.


A great shop. I have a 10-year old car - a Kia Soul, so a bit of an unusual make. The transmission was having serious trouble - from age and my own tendency to ride the clutch. KPS was fast - returning the car ahead of schedule and beating my own initial expectations. They were courteous throughout, and the cost to replace my transmission was far better than my expectation, especially given the location, so close to Princeton. I will definitely be coming back to this garage.


KPS was able to identify the problems and find a cost effective solution to a no start and having no AC. When the check engine light came on after the repair was complete, they made sure to identify the problem on their time with no cost to me! The owner is a knowlegeable and honest mechanic, which is rare to find these days!


Great service, friendly staff and helpful. Had the vehicle ready as promised.


Professional and courteous service! What I like is that there are never any surprises. My first choice for any auto repair


I HIGHLY recommend KPS Garage. The owner is very professional and explains in detail what he is going to repair and it's very well priced. I will returning to this garage for any future repairs. GREAT COSTUMER SERVICE.


Mark & Bob are great - they run a thorough and trustworthy shop


Fast friendly service. Will definitely be back


Diagnosed and repaired a significant oil leak. As always, done well and in a timely manner.


Great mechanic, my parents have been going to him for years and the whole crew is wonderful.


Service is friendly and quick


Friendly group of guys who were no nonsense, fast, and at least one of them has been known to go to the theatre on occasion. What's not to love?! Thank you!


Little wait but good service.


Changed my TCU. Thank you for all your help! Thank you for being thorough and helping me resolve my issue.


I have found them to be reliable and reasonably priced for general maintenance. In addition, I trusted them with rebuilding the engine/trans of my "hobby" car- a pretty unusual "hotrod". Nobody else would touch it. The engine work was done right. Since it is a "hobby" car, I was in no rush to get it back - - - All the work DID take time but I've got it back now, and it's running strong.


Pleasure to do business with them.


They were able to fit me in last minute and at the end of the week when my battery stopped holding a charge. Great service!


My 2007 Jeep Wrangler had some front end issues and a Check engine light. The guys at KPS kept me informed through the repair and everything came out great. Thanks


Always excellent service, and work well done. Crew very easy to deal with.


Coordinating representative Mark and Owner Bob were the utmost professionals. Their shop was very thorough with my truck project and I liked their use of technology (pictures, text, etc) for up-to-date communications and inspection details.


Pleasantly surprised!! The current labor shortage has been extremely challenging for many small businesses. There was a miscommunication with my customer experience at KPS; however, the team was able to quickly rectify and extend their most genuine apologies. KPS is fairly priced and has a team of honest and highly competent technicians. It's no wonder they've been in business for over 30 years! I'll be back! Thank you.


A trusted source.


I went in for a severely flattened tire. KPS Princeton Garage not only found the rather specialized tire, mounted it with balancing, etc. and road tested, they also alerted me to another problem. They suggested that I should go to my dealer with this problem, since it was likely to be covered under warranty. I did, and it was! So they saved me a lot of money by not doing the work themselves. Many thanks! This year I had another flat tire (Chevrolet does not provide or even sell a spare for the Volt). KPS Princeton Garage not only fixed the tire, but told me that the dealer's advice that I needed new tires was greatly premature. More money saved.


I have always found KPS to be honest and helpful when I need work done. I appreciate their help and attention.


Excellent service. I went to them because a friend had used their services and I have been very pleased with the time it took to complete the repairs. Will be going to them for auto service again.


The car wash service is very thorough, taking about 45 minutes while you wait, but worth the approximately $20. Call to make an appointment for this service.


Have been going to KPS for about 6years now, everytime I drive out of there, I feel the car is renewed and the required job is done just right. They know their stuff and have never disappointed me


I was looking for a great mechanic that has experience working on Volvos. I normally bring my car to the Volvo dealer and let them service the car, however I was looking got better service at an affordable price. KPS was recommended and they did not disappoint. They are professional, transparent, affordable and great customer service. They are officially my new mechanic! If you're looking for honest and affordable mechanics look no further! They will not disappoint!


Great guys! They've always done a great job with my car, are good with updates about the work, and the owners seem like genuinely nice people


This is my go to independent shop for all my car's needs. They have always done a solid, cost & time efficient repair. Never had an issue getting an appointment - drop off/pick up locally if needed. Have never felt like they are trying to take advantage of me or require unnecessary repairs.


I had to get a part of the steering replaced and dropped off my car in the morning. It was ready later that day, as promised. I'm very satisfied with the quality of the service and that the repairs were performed on time, as promised.


Great local shop. Working hard to support local people. Become a regular here and get great service and attention.


I have relied on Bob and his team for years for numerous vehicles. They have solved problems dealerships couldn't, expedited repairs when I was in need of immediate service, and gone out of their way to help me out. Always eminently fair, honest and professional. They fix something the first time and it stays fixed. KPS is the best, hands down.


They are always reliable and efficient. My new car repair place!


Excellent, friendly service.


I went in for a severely flattened tire. KPS Princeton Garage not only found the rather specialized tire, mounted it with balancing, etc. and road tested, they also alerted me to another problem. They suggested that I should go to my dealer with this problem, since it was likely to be covered under warranty. I did, and it was! So they saved me a lot of money by not doing the work themselves. Many thanks!


Very satisfied. They don't try to sell you unneeded repairs. Service is great especially for those who live locally. They even dropped off my car back at my house. Fair pricing and trustworthy. It's good to have a local garage you can trust.


They "babied" my car through an undiagnosed illness...asking me to drive it and if a certain light came on, to bring it back...this lasted about 2 months...and finally after considerable diagnostic work they knew what the problem was and that it WAS covered by warranty still...It was fabulous detective work on their part and the car went to the dealer who repaired it for free...


Always know that everything is done right the first time! They are always efficient and safety conscience.


KPS is what every car owner hopes for - a fair, honest, and local repair shop. These guys are nothing but professional and are always my go-to when I have a vehicle issue or need regular maintenance. Thank you as always KPS!


Effective, timely and thorough services - as usual!


Like the people there. They are fair with the pricing and I trust their work. Plus just outside my complex where I live. That's always good.


Always get great help with whatever issue is with my car. They are very fairly priced, never feel ripped off, service manager is great.


Jessica ?????May 2, 2021 Been going to KPS for over 5 years and I really trust the mechanics here. They do a great job from repairs and oil changes to interior detailing. Not to mention fantastic customer service. I moved about half hour away but still make the trip to KPS because I know I can trust them.


Honest guys who do great work. Would recommend


They replaced the boot joint in my VW in half of the price than the quotation given by the dealership. Did a great job with the repair. Mark was very nice and friendly.


Great dependable service as always. I like that they check tire tread and brake pad use at every oil change and take the car for a ride before working on it to get an impression on how it is performing.


My Volvo 940 suddenly stopped when making a turn at an intersection. Had it towed to KPS Princeton Garage. They found that the problem was a defective ignition coil. They replaced the ignition coil. They did a good job and at a reasonable price. Would recommend them.


K PS has always provided us fast, reliable, transparent repairs and tire changes. On Valentines weekend 2021, despite having reduced staff they were able to get us in to put snow tires on our cars promptly. This is a very well run business. They hear and take care of our concerns. I will continue to use them in the future and refer them to my friends and family. Deep T. Monmouth Junction, NJ


As usual KPS folks are very customer focused. You can always count on them to do good and reliable work on you vehicle. Prices are fair and the staff is very courteous and friendly. Bottom line, I highly recommend these folks!


As has been the case for the last 15 years of patronizing your shop, I thank you for your advice, honesty, and respect for my budget. The car feels wonderful, the detail work makes this 10 year old vehicle seem new again. KPS is the only shop I would ever bring our three vehicles to for service. I highly recommend to anyone looking for an honest and reliable repair center.


I just wanted some information about service and gentleman was so patient and professional.

reviewiconReasonable Prices

Great service and reasonable prices. Feel confident in their abilities. Have recommended to numerous people and all have been pleased.

reviewiconDefinitely Recommend

KPS has kept my car on the road for years. They don't overcharge or make unnecessary recommendations/repairs. Definitely recommend.

reviewiconMagic Touch

There are few mechanics left who have the knowledge in their heads and not just a book or a code on a machine....This shop has that magic touch...

reviewiconBest Auto Shop

I have been using this shop for some time as my go-to service center for all of our family vehicles. In every occasion, they have called before performing work,been prompt and reasonable with work performed and all around easy to deal with. There is a value of returning to the same spot when after a while they know you by name and treat your vehicle like that of a friend's. Go here, become a regular and support the local economy. They may not be the very cheapest every time, but I've never known them to cut corners either.

reviewiconAmazing Service

KPS in Princeton did a great job fixing my BMW 750 they kept me informed about what they were doing and when my car would be done they were extremely professional and not expensive two thumbs up to KPS

reviewiconFast and Courteous

Seriously, bring your car to KPS. The Yelp reviews are horrible, but KPS has 27 awesome reviews on Tire Rack, so I went anyway. I'm happy I did. I ordered tires Thursday night before a holiday weekend. I took my car to the shop on Friday at noon and demanded that my alignment and tire mounting, balancing, and rotation be finished before 5 so I could leave for vacation. And guess what? IT WAS! The owner even drove and met a UPS truck to pick up my tires and make it happen! I'm very pleased with the work and service.

reviewiconHighly Recommended

This is my preferred auto repair shop in the area. Have been using for 5+ years on several cars. I have always been satisfied with the results.

reviewiconHonest Auto Shop

My wife and I are new to the area and KPS Garage was recommended to us from a neighbor and we couldn't be happier with the service and work they performed. They are very accommodating and honest we won't go anywhere else.
