Samuel R.

I recently purchased a 2009 Dodge Journey that had been sitting for over 6 months. It needed a new starter and was misfiring horribly and making an awful knocking sound. They did a complete check on the vehicle. They checked spark plugs, compression, fuel injectors and even removed the catalytic converter to check if it was clogged. Finally they checked the timing and found I was misaligned by 3 teeth. Moreover, the belt tensioner was bent to hell. They fixed my car in one day. I'm extremely satisfied with their work. When I pulled up to pick up my car, I found one of the techs shining up the front end of my car which was the extra touch that impressed me. I will return with all my future needs and recommend Diego's Mechanics to everyone who wants quality work at prices that don't break the bank.

Always good to have a seat

This place is fantastic.. family owned , friendly, great prices ....they are very knowledgeable and explained exactly what was wrong and how much it will cost ... I have recommended Diego's to several friends and they were all happy to have gone there ...pete

In this day and age you want to go where you can build a relationship with those who work within ypur life, that you will surely need for years to come. That's why I choose to come here to Diego's Mechanics at 429 West Main Street in Stamford, Connecticut 06902. I first learned of them a few years ago when my car died at the hospital. They towed me on a snowy day and saved my Greta. She needed a new starter. Now it is time for an oil change but could really use a tune up, which is what Greta got. Diego was such a help. Great work and not crazy prices like a dealership. Bring your Betsy or TomTom in for their oil change. They will thank you by running you around without choking on old oil but the new, fresh gold that has cars purr...

See all

Paid over $330 for a "diagnosis". Left my car for three days while they were "analyzing the…read moreproblem". After three days I got a text telling me that they inspected my car and "there's a problem with the transmission." REALLY? REALLY?????? They did not identify a problem. "Something is broken inside" does not sound like a diagnosis. The only diagnosis was to tell me that I could spend ANOTHER $2000 for them to "break it down on the bench" and find out what was wrong and THEN it might cost ANOTHER $3000 to $5000 to actually fix something. I wonder why I spent over $330 only to be told the EXACT same thing that I told them when I drove in, "Something is wrong with the transmission". I have no idea what kind of actual work this place does. All I know is that they took $330 of my money and gave me nothing in return. I feel cheated. I believe that an honest mechanic deserves to be paid for his expertise, his knowledge and for the work that he accomplishes. Like any professional, his time is valuable. But an HONEST mechanic does not charge customers for promises made and not kept. He does not charge hundreds of dollars when he knows that it is just money down the drain. An HONEST mechanic would tell people up front that they cannot get a diagnosis for $330. An HONEST mechanic would tell customers that a diagnosis will be much more expensive because it involves so much work. Yes, a two thousand dollar diagnosis would chase away some customers, but at least it would be truthful. Even though this is my first car and I don't have much driving experience, I still knew that "something is wrong with the transmission." This was a con. What I got for my money was just an expensive lesson in human dishonesty and greed.

I was referred Croce's by another local automotive business (who THEY use to get transmissions…read morerebuilt, fyi), for a potential transmission rebuild and/or torque converter replacement. Tony and I took a test drive, after which he suggested my problem was NOT in my transmission... He had high confidence and made suggestions on next steps to diagnose some noises/problems I was having. Tony spent almost 30 minutes with me... I offered him money for his time and he refused. Top notch, locally owned and I would highly recommend them based on this experience.
