Even though it was minor stuff like plugging a tire or car inspection Armando was very helpful , a couple times he wouldn't even take $ . I highly recommend this place , it's hard to find honest people and help like this place has . read more

Quick, reliable and TRUSTWORTHY! May I need to say more? That's why he is busy, His shop has repeat customers obviously for a reason. THANKS! read more

This is the only mechanic I trust with my cars. Excellent service. They never try to sell me services I don't need. Will definitely return.

My check engine light came on today. I was no where near home and concerned that I might not make the hour and a half return trip home. I looked to yelp for a local repair shop that could at least diagnose the problem so I could know what to expect. After reading reviews, I decided upon D&D. I found the shop attached to a gas station and it looked busy at 2:30 in the afternoon. There were several cars parked around the shop and all the bays were occupied with mechanics at work. I wandered to the back of the shop and was promptly and politely greeted by Armando. I explained my situation to him and half expected him to tell me they wouldn't be able to get me in before the day ended. Instead, he said, "sure", grabbed his device and waited for me to lead him to my vehicle. Surprised, I directed him to my car and in less than 5 minutes he told me that my catalytic converter was going out. Since I know very little about automobile mechanics, I asked Armando a few questions about the nature of my problem. I found that I easily trusted his advice and while it wasn't good news, I knew I would likely be able to make it home to my local repair shop. I immediately wished that D&D were closer to my home as I would choose them over any of the numerous other repair centers I have tried. The service I received from Armando today has everyone else beat by miles. Thank you! read more

So my brakes where squealing on my new car 2008 Cadillac, my first thought was okay I need new brakes. I brought the car to Dennis at D&D and he called me and said my brakes where fine. I went home and pulled off a pad just out of curiosity and they are a little glazed from me braking hard, but don't need to be changed there's plenty of meat on them. Jesus, he could have easily swapped them out with new pads and charged me. But he didn't, he did the right thing. Honestly I couldn't say enough about the integrity of this shop. Bringing my car in for an oil change asap and I feel so comfortable with these guys, it means a lot to have a trusty mechanic. read more

Great mechanic, No song and dance. fair and honest. I use them, my 2 sons use them, my 2 brother in laws and their families us them. That should say a lot. If you are looking to try someone new, they are worth a try. read more

I agree with the prior review. Dennis and his crew are great mechanics. Reasonably priced and honest. I recommend this repair shop 100% Tracey Nixon read more

I would like to give a huge thumbs up to D&D Diagnostics in Farmingdale. I recently had some car troubles and went to another place (they shall remain nameless) before them to be told that I needed to find the parts myself bc it was dealer only. I don't speak car language and was armed with useless information. I finally went to D&D Diagnostics after some folks recommended them on a local FB page and so happy I did. They looked at my car and told me the issue and give me my options. They went above and beyond to find the parts and fix my car even though they had to work past closing time. They were honest and reasonable. If anyone wants an honest mechanic speak to Dennis. read more

This is probably the best mechanic shop on Long Island. I took my car here for an oil change and they took care of it in a very timely manner and went the extra mile too. They made sure my tires were filled up with air and reset the pressure light. They even filled my washer fluid. I even asked them to check over the car to make sure everything was okay. The owner Dennis said everything looked fine and was VERY honest and helpful. They gave me a very reasonable price to have my brakes done in the future. All of the mechanics there are very hard working, knowledgeable, and friendly. I trust them 100% with my vehicle and I recommend them to all of my friends and family. I have had bad experiences with dishonest and rude mechanics before (McBirney's Auto service) and I am very weary now with who I bring my car to. You cannot go wrong with this place. I cannot recommend them enough and I will always bring my car here. read more
