My positive experience supports those of other customers. They are honest and Fair, in my recent experience. My 1996 Camry sedan had a "Check Engine" light (Aug4.2013) that coded for an Igniter problem, and the engine simply shut off intermittently during coasting, six times in one day --- but any of FIVE components could have caused that code. They had my car in their shop hooked up to a testing instrument array that takes 45 minutes just to attach the leads, and they also drove the car for 20 min to try to duplicate the problem. Three days of testing but no charge since they could not reproduce the problem. Otherwise it would have cost about $640. No Charge!. The rental loaner was also no charge. I had used them just once before, also with free loaner.The average garage would probably have replaced one or some of those five expensive components, hit-or-miss, and charged me $$ or $$$, probably without correcting the problem. I'll be observing the car now while driving to see if there is some quirk of actions needed to elicit the problem, or if it even still occurs, and will take it back to them if I find a way to reliably reproduce the problem.
