So these guys are pretty awesome! My car was misfiring. The first place I took it to said it was just my o2 sensor...it wasn't. The second place was going to charge me upwards of $500 just for the diagnostics. Ron quoted me a reasonable price to perform the diagnostic tests. They also charged a reasonable price for labor and gave me a list of the other work I need to eventually have done. These guys are honest and fast. I'll be going back to them for sure.
