Engine repair service near Diamond Bar, CA

Roger and his staff were excellent. Gave me a great price on a tire and did an amazing job! Definitely recommend this place to those looking for great customer service and prices. Luis Saldana

Overpriced with a "can't tell me sh*t" attitude. Maybe their great on old cars but as for my wife's 2010 Challenger they caused more issues then fixed and charged me 1/3 more then anywhere else to do it. Brought my car in for springs, struts, alignment and to go through and make sure everything was right. Did a motor swap and the shop before didn't tighten the lock nuts on my adjustable suspension so wanted it all gone over. Guy was mouthy from the start and bitched about the job the whole time. My front ball joints we're missing a lock plate (found out later), really obvious but they didn't say anything and put it back together anyway. Also missed my rear craddle bushings went bad even after bringing it back to them. This is a huge issue and made the car unsafe to drive, they said it was all good though. I call back and kind of question their knowledge since these basic and obvious issues were missed to which I was hung up on. My advice, find another shop and save yourself the agony.

Jack took care of my flat tire and balancing at no time, very early in the morning when other places were all closed. He knows how to take care of his customers. Fair prices. I highly recommend services on this place. Malaga S.

If I could give six stars, I would! It doesn't get any better than Tony's! Crist M. Pico Rivera, CA
