Shirley Lomeli, 07/08/2026Art is your go-to trusted expert and a rare, extraordinary genius, kind and funny mechanic!! Very lucky to have met Art and have his outstanding help to resolve all my issues on my older vehicle that had several serious electrical problems (parasitic drain, instrument clusters on dash no longer working, and my driver seat button no longer worked) that no one else could help me solve!! Art is so smart and hardworking! Art is also very quick to get the work done especially considering older vehicle parts are very difficult to find, and yet Art kindly charges a very reasonable price. Art also replaced my badly leaking radiator thanks to him for carefully noticing this before I had an issue! Art was well worth the further distance I had to drive to but worth every mile! Art is very much loved and appreciated! Thank you so very much Art and for taking such amazing care of me!! :) You are the Best!
