Richard has been my family mechanic for years. He is patient and explains the how and why concerning repairs. He prices are fair and reasonable. I've not had any issues on the work he's completed I would give A and B Diagnostic five stars only when he acquires a bigger freestanding establishment.

Richard was professional, honest and reasonable. Had service done to my Chrysler 300 for two different issues and I’m pleased with the work that was done. I will continue to go to him for any auto work needed for now on.

Dishonest and bad mechanic. He said my transmission needed fluid. I paid him $320 to fix it. After he said, oh its your power steering...but still charged me. Then that night my driveway is covering with fluids. I take it to another shop and my transmissiin is leaking, power steering hose is leaking and so is a heater, so not only is he dishonest, he is a bad mechanic...women beware. After my minivan was at his shop I spent a thousand at Firestone and $900 at Aamco .I think his coworkers made all these positive reviews.

The owner Richard is very thorough, very kind and does a great job in repairs. He takes the time to properly diagnose the problem and has affordable prices. I've had 3 different cars serviced here and not once did I ever have to revisit for the same issue. He also warranties major repairs. I had a new transmission and fuel pump replaced on an Armada. Felt like I was in a brand new truck. My whole family has had service here and we all have different year make and model cars. I highly recommend especially for the ladies. He's not looking to get over on us. He's more concerned about our safety and kids and budget👍👍😉

I have taken my car here a few times and every time my car has been taken care of by Richard! He offers great pricing and most of the time the car is ready within a few hours or less. He is very passionate & knowledgeable at what does. He explains everything very detailed Leaving you without any doubt . He is a great mechanic I highly recommend him.
