For feck sake...its unbelievable the amount of ar$eholes going around our streets these days, it really is. Sorry to hear bout your car chris, im sure weve all had sh*t stuff happen to our cars and thats one of them.
My advice is to not sell up, the car looks amazin, really nice, and the more stuff you do to it, the more people will be jealous of ya. Right enough, lets hope its the right kinda jealous cnuts eh?
Probably not much help, being from Cheshire, but if your ever up near my end (Glasgow) soon, check out Campsie Couchworks (John Lynch) 01360311771 - say Chris w/Clio and Andy w/Soarer said to u to go. My door got wrecked badly a year ago, sorted it for 300 quid. He recently put on my coilover kit and did my bumpers for 200. Basically, really good guy. Long shot, but, hey, sometimes it helps.
Another thing, at least you and your mate were ok, what was to stop this guy opening the door/smashing the window and stabbing one of you in the neck?
Its good news on you taking action against this scrote - lets hope something comes of it, if not, blow up the f*ckers house
