These guys absolutely saved me!! Last August I was many miles from home (from Chicago), and my car suddenly had an issue on the highway. I was sent from AutoZone to these guys, and I couldn't have gotten a better place. Thankfully they had time that day to squeeze me in to diagnose and fix my car. I could tell that they are honest people and the owner really knows his stuff. He explained exactly what was wrong with my car, and they were professional with me the entire time. They even filled up my break fluid for free since they noticed it was a little low. Without their help I don't think I would have been able to drive back home. Truly thank you.

Bill & his team are real pros. I ve been a loyal customer for +10 years. Bill takes the time to explain the issues he s discovered, presents repair options and has very fair prices. Only place I will take my Audi - he s usually half (or less) the cost of going to the dealer and he uses original Audi parts.Services: Air & cabin filter replacement, Tires, Auto exhaust system repair, Auto engine diagnostic, Vehicle Inspection, Brakes, Auto maintenanceServices: Air & cabin filter replacement, Tires, Auto exhaust system repair, Auto engine diagnostic, Vehicle Inspection, Brakes, Auto maintenance

Bill and his team are the most honest mechanics around. My Mother and I have known Bill for a long time and been going to him for YEARS. He is the only one we trust to work on our vehicles. And no matter the problem he fits us in immediately and gets things resolved as fast as he can! 10/10 would recommend his shop for any needs you may have!

Premier auto service in greater Lowell. Staff knows their stuff, honest and competent. They will present different options if available and work is needed. I go here with a new car. They are that good.

Bill is the best mechanic I have ever worked with. He really knows cars, and he really cares about people. Ignore the disgruntled reviews from losers who didn't like his attitude. Bill is honest and very knowledgeable. He has gone out of his way to save us money, and he has never been wrong in his assessments. We have taken our cars to him for years and years, always with a very positive result.

Always reliable. Fair prices. And I've never had to go back because they failed to fix an issue. If you're looking for a great mechanic, don't go anywhere else.

Fair prices, knowledgeable, dependable. I had a hard time finding a mechanic I could trust after moving to the area a few years ago. Bill is great, I bring all my vehicles here and refer people to him whenever I can.

The gods of auto mechanics have truly shined on me. Not only is Bill and his staff extremely talented and knowledgeable and fair but they are literally around the corner from my house which makes dropping off and picking up my car so much easier. Me and my boyfriend use him now and he is always timely Fair and knowledgeable. I had something wrong with my old car and he told me it wasn't worth fixing and that it was okay to drive it. That alone earned my trust forever. Be warned he's very busy and he might not be able to get you in immediately. But he's worth the wait.

I have been gong to Chelmsford diagnostic for years for our cars . My husbands family have been going here for years. I find them friendly and knowledgeable about the cars Bill always tells me what I can wait one and needs to be done today to be safe. I love going here and I highly recommend them to all my family and friends.

Very satisfied and relieved. Bill and his team diagnosed and fixed a serious shifter problem with my 1997 Jetta. They performed the work as promised in the most professional and courteous manner. They will be my go to shop from now on for both my cars. Great service and knowledge on their part. Many thanks to them.

In my opinion, the staff here are very unpleasant. I came in for inspection, they didn't do it right and so I couldn't get my MA plates. I came back to them and they told me it was my fault they did it wrong, they didn't offer to redo the work, and when I asked what I have to do to correct the inspection, they told me I should go to another inspection center and start from scratch. I did and everything was done quickly and with a smile.I recommend avoiding this place. There are many other businesses in the area offering the same services and they are much more helpful and pleasant to work with.

We are a 37 year old business with a fleet of sixteen vehicles. We have trusted our vehicles to be properly serviced by the folks at Chelmsford Diagnostics for over 15 years and have been very pleased with their prompt service and fair prices. They maintain our vehicle service records which is helpful when it is time to retire and sell an older vehicle. Occasionally, if we have a breakdown they always come to the rescue.It's hard to find service like this these days.

Trustworthy service at a fair price. Honest treatment is exceptionally rare in the auto repair business. Chelmsford diagnostic services takes care of everything with care and detail. Always an accurate estimate before the work. Fast turn around. Bill is in a word, trusted. Inspections to tires, all the mechanical stuff. No body work.

Trying to do inspection here, drain my battery and failed my inspection. Staff are rude and refused to do a free retest. Had to ask an police officer step in. Also receive many scam calls and mails after the first visit, should avoid any service here to protect your privacy.

The guy in the front is stuck up and rude. Always has an attitude at least with me. You would think handing him over $900 for a brake job would put a smile on someones face. Nope not this ignorant guy. 6 months later and have to replace all 4 pads and rotors again. This place specializes in diagnostic repair. It is even in there name. 2 trips and $200 for diagnostic tests yielding no results and blaming it on dealer parts. Turns out there tech had put one of the sensors in the wrong slot. Dealer found in few minutes and was only $60. I have tried this place because they are local but every time we have tried to do business we have been over charged for basically nothing in return, and the guy in the front makes you feel like you are inconveniencing them. Over $900 for brakes and I'm inconveniencing you. What a joke.

Very knowledgeable, when trouble shooting my vehicle. Bill told it would be ready today and it was. Very happy with The results. I would use them again.

I go out of my way to get here for major repairs and maintenance after experiencing some deceitful practices at other shops. Repairs here are done right the first time with up-front disclosure on parts being used -- usually meaning more of the cost is going into quality parts rather than inferior parts with inflated labor.
