Personal service by owner Bill. Average prices comparatively - but most importantly- he's honest. A host of non English speakers on weekends which is always annoying in trying to communicate. Walked in to pick up car and stood in office unnoticed while they were jammering away socially in the garage area. I had to go out and break up their party to get service. read more

I brought my car in unexpectedly and dropped it off. Bill was able to fix what Mr. Tire tried to do and failed 6 times. Bill is a good guy who goes out of his way for you!! read more

The best auto repair shop in New Jersey! Always a great job and fair price, and friendly service.

Denson's was recommended to me by members of our local volunteer rescue squad of which I have been a part for more than 23 years, and that is just about how long I have entrusted my cars to Denson's. read more

Tried this auto repair shop for the first time 9/2021 after reading good local reviews for my 2010 BMW 528i. I had already been to the dealer and to another place that could not fix my issue. Bill and the team took care of it and the other issues I had been dealing with. They topped it off with an inspection all for a reasonable price. This is my new Go-To auto shop. Excellent job. read more

Honest, reliable auto shop. Gave me a quick appointment and honestly told me what needed to be done in a few months. Will definitely go back. read more

This garage is the best. I've used them almost exclusively since moving to the area, and they came HIGHLY recommended. Excellent diagnosticians, on time delivery, and very fair prices. A pleasure to work with- I know this garage will always do the right thing for the customer read more

My wife and I have been going to Bill Denson's for a couple of years now and having nothing but the best to say about every experience. The prices are great and the work has always been great. On top of that he is a super nice guy. I love being able to support a local shop and proud to call it my local shop. read more

This is probably one of the best auto repair shop in the area, very efficient and courteous people, would highly recommend

Billy has taken good care of our cars for years and I have sent friends his way with 100% confidence. Whether a routine oil change or perplexing problem, the job is always done right and completed as promised. Take the money you save (vs dealer), have Enterprise of Green Brook pick you up, with money leftover for a nice dinner out. While he specializes in German cars, do not hesitate to bring just about any make/model in. A damn good problem-solver and an honest, righteous dude, he is. Gas is a bit more expensive than than on Rt 22 but a helluva lot more convenient. And who else has free air (for tires) anymore??? read more

We take all our cars here to be repaired. They do a good job every time. And their prices are the same as any other auto repair shop. Dealing with them many years, the are honest. read more

Nice people to talk to, fixed our car's problem once and for all when other places persistently couldn't. The price isn't that cheap but they are good at fixing cars. read more

Been going to Denson's for 35 years. Fair prices, excellent, competent, and friendly service.

Best VW Audi shop in the area bill sr , jr and ray have been there when I can't fix it and the price is more than fair been coming here for over 20 yrs and never questioned the quality of the work if you own a car bring it here nothing they can't fix for a great price read more

My father used to bring his cars to Bill Sr. back in the 70's if it was something we could not repair. I was away for 30 years and moved back 5 years ago. Found Bill Jr, In Martinsville and have been going to him with anything I need done, You cannot not find a more knowledgeable and honest group. They do not over charge and stand behind their work. In fact Billy looks for ways to save you money. His reputation is beyond reproach and his knowledge of cars an problem solving is among the best in automotive world. Even if my car was under warranty these are the only guys that I would allow to touch it. read more

I just met bill today. The guy is an honest to God saint. I was borrowing my moms brand new Jetta and a curb loosened my front bumper big time. I called densons on a Saturday evening, told bill my tale and he worked me in on Monday after work. Now that is accommodation. After 30 minutes, he fixed it perfectly and said I only owed him 25 bucks. 25?!?!? This guy is down to earth hard working and most importantly honest. Anyone else would have probably screwed me into getting a brand new bumper and charged me an arm and a leg. But not bill, great guy, I would recommend that anyone who appreciates high quality work at honest prices to bring their car troubles here. I'll send my family and friends your way budd. read more

After dealing with Billy Denson for the past 5 years, I've never had a problem, he is honest, I take our 3 cars there. Once He felt when my ac compressor went for me to check with the Infiniti dealer to see if it may be under warranty. with 85000 miles on the car, I highly doubted it, but sure enough it was. I could go on and on with other stories, but you get the point. He always greets me with a smile, even when the gas station is packed with cars. read more

Densons is a family owned and operated auto repair garage. They are honest. Fair priced and very quick to move. They specialize is foreign cars but I'm sure they can repair any car. read more

This review has been long overdue - I have brought many of my vehicles to Bill for work in the past and he has always been honest and charges extremely reasonable prices for work. I am very specific as to who I have work on my Mustang, and Bill always takes great care and performs nice clean work on everything. I have even referred my mother-in-law and brother-in-law to him as well, and Bill took great care of them at a great price to help them out. read more

Nothing but great things to say about Denson's in Martinsville. I have taken both domestic and import cars there over many years, and both Bill Jr & Ray have been a pleasure to work with. I just recently found out that Bill Denson Sr, has closed Denson's of Somerville to work with his son at Denson's of Martinsville, making this a mechanic's powerhouse. Highly recommended! read more

Took my truck in to get my rear window fixed and was told there might be a problem with the power steering. I told him to just fix the window for now but when I get the truck home the power steering is leaking like crazy. My driveway had been clear of any stains and now all the sudden the fluid is draining faster then I can put it in. read more

I have known Bill Senior and Bill Junior for years. I have a Landscape business and they do all of my work. Alway fair and always on top of things. They really know what they are doing and can fix things the first time even big jobs little shop may shy away from. I had a problem with a turbo oil line. They get hot and rusty on work trucks and are near impossible to remove. Bill told me he sat there with a torch and a four foot bar turning the bolts a quarter turn each time. If they broke off what a bitch. I'm sure another hack mechanic would break them off and tell you need a new turbo. If something is not busted he will check it out for nothing and send you on your way. I'm sure the dealer would sell you something. Always busy for good reasons I hope they can keep up with the piles of cars in the lot. read more

Bill and his team blew my expectations away again!! My truck now has ice cold AC and what I thought would be 1k turned out to be $150! Very happy and highly recommend this repair shop. read more

I have taken my car to them for years. I have an Audi Q7 from '08 . . . Bill Jr told me to sell it or it would start costing me big money in repairs. ( He might have made big money on me and my car . . . which other dealer would tell you this and loose on making your repairs?) HIs prices and always more than fair . . . and always makes time for you. A saint! Cecilia S. read more

As honest as it gets...They do good work. As long as they've been open i've never had an issue. My whole family goes there because Bill D will always steer you in the right direction. One time i had convinced myself i was looking at hundreds, if not over a thousand dollars in repair. When he checked under the hood, he came back with a smile and said that a hose had come undone(something to that affect) Left the garage with a smile, my wallet happy, and my van running smoothly. You commonly see high end cars in the shop right next too old mini-vans like mine also. There's not alot of people who have great talent and honesty out there, let alone having one of them be your mechanic. read more

How refreshing to have an honest, reliable, hardworking repair shop that you can trust! I've been a loyal customer for years and have referred friends and family who are all now life long customers! They are always very busy but will squeeze you in if you need them to. This place rocks! Their business practice is so solid they will need a bigger garage in no time. Take a bow Densons, you are such an asset to the community! read more

We have taken all of our cars to Bill over the years and he has consistently given us excellent service at a very reasonable price. I highly recommend his shop. His right-hand man, Ray, is also a straight-shooter who is very skilled at working on any type of problem from a simple oil change to a new brake job and replacing tires and cracked rims. They are great. read more

Was a customer for years. I brought my SUV for repair. The 4WD wouldn't engage. It looked like it was stuck. I called them and was told I could have it towed there. I wanted an estimate. When I called to find out if they had an estimate, I kept getting bounced back and forth between father and son. Finally after day 5, I had them disconnect the FwD so the light would go off.. Did it really need to be disconnected if it wasn't engaged? I was charged $300+, and still no estimate. Wasted my time. If they didn't want to fix it they should have told me. Found out later that the rear axel housing was rotted. Something that didn't occur overnight and was unsafe to drive. Never informed of this. Earlier in the year they fixed the check engine light (never asked for that repair), charged $400+. Check Engine Light came back on in a few days. No explanation why or a refund. Found out later that there were Cat Converter codes, that is why it came back on right away. Only the Oxygen sensors were replaced. What a waste of money and time. Wouldn't bring my car to be repaired here if it broke down in front of the place. read more

I have been taking my cars to Bill Denson for over 25 years. He has taken care of everything from an RX-7, to a Corolla, to a Miata, to minivans, to an Infiniti, to BMWs, to Porsches, to Scions, to SUVs. Both Bills are the real deal. The two most important things that anyone can say about a mechanic are that they are honest and that they know what they're doing. The team that Bill and Bill have assembled has proven to me over, and over, and over again that they are both: honest and reliable. I live in Hillsborough and went to the shop on Route 206 for most of the time I've been using Denson's. Since they had to close that shop, I've been going [all the way] up to Martinsville to have them work on my cars. Our family has 5 cars and Denson's does all of our work. They are a treasure and I couldn't give them anything but the highest recommendation, for any repair. read more
