Tony and Norma are the best Auto team you'll find around. I took in my beat up 1997 Toyota Celica not knowing where it was at in health, suspecting the transmission fluid may have been way past it's replacement due date. Norma kindly gave me a quick ride back to work (dropped it off on my break) while Tony took a look. Got a call back and was told everything was in working, proper order. I don't know much about cars yet, so any mechanic could have taken advantage of that and tried to sell me something I didn't actually need, but not Tony. Had a great conversation with him after the fact, and he clearly knows his trade inside and out, giving me extra tips to maintain my car. Finding an honest mechanic with Tony's skill is an absolute rarity, and the fantastic customer service from Norma is refreshing. Definitely coming back whenever my Celica needs service.

For me, trusting a mechanic I don't know if very difficult. I took my 85 Ford Bronco to Tony for a Smog Check and/or Repairs. He actually had to do another job which I was aware needed to be done. When it was all said and done, this man went above an beyond what I would have expected. Even though he did a few extra things, he charged me exactly what was quoted. Awesome experience! I will return!
