I never let ProToy work on my car, but have met the owner several times. I first met him when i went to check out a mk3 that he had believe it or not. He was claiming 350 hp, and i hadnt had my car too long, so i figured id go check it out. So we talk for a few, and then he pops the hood and there it is... a mk3 N/A motor with some big nasty truck turbo on it. he then proceeds to tell me that it was originally a turbo motor and yadda yadda... the distributor and plug wires, among other small descrepencies, must be because it was a canadian model.... right. so then he tells me how fast it is so we decide to go line them up. his 350 hp beast to my 260 hp beast. should be no contest, right? I spanked him, from a dig, and a roll. so either he's full of crapola, or he cant drive. A couple weeks later he blew the headgasket and sold it.
I've also dealt with him when i worked at Advance Auto Parts, he bought from the store i worked at. he really never seemed to know what he was talking about or trying to fix. I could be reading too much into it, but i'd never let him touch my car.
just my opinion i guess, since i've never let them work on my car, but first impressions go a LONG way.
