Guy who does mine hardly know the guy but every car i take there passes.
First time I took a old 1999 ibiza in, two tyres on the wear bars, wishbones dead, balljoints dead, exhaust blowing. he drove it in, let it run for a bit, put the washers on checked the lights went underneath it for about 30 seconds then passed it, didnt check brakes emissions or sod all lol
VW he passed next took even less time, i know its dodgy but i 90% of the time know what a car needs doing so i fix it anyway but if it was some dipshit woman or a old granny it would be a different kettle of fish.. :/
