Not sure mate,combination of things I think.
Spent 5k on it to get it around 400 bhp,exaust,cams,ecu,injectors.
That morning was snowing,plus I had heavy night before.To cap it all off got done for being over the limit.Luckily I got paid out on it.
Have to admit it's one of the best cars I have had,but that was ten years ago.But when I saw that r34 in purple makes me think about another.
