Thats the only reason one could ever be called a chav car IMO! as standard they look pretty normal, no more chav than any other jap sports car of the era.
Although the supra is a bit of a chav icon of worship, but not as much as the skyline
'isit a GTR mate? twin turbo innit well easy to get a faazand brake aht of that mate'
or the subaru impreza
'yeah is basically a rally car on the road innit mate does 0-60 in abaaat three seconds and is quicker than a cossie innit'
T.F.A.T.F. movie did us no favours
Luckily I will never have the chav thing, as most of my cars end up looking like something out of mad max, which I like as people hear a loud exhaust, look round expecting to see a tarty car and then thier face changes to a look of confusion...
