Innit clart...
Love it. It's more than likely no fault of their own, the various people who've actually commented on this like it's a serious car modifying flash or somethings, guess that's what happens when you don't know of any culture outside you're own state ;).
Also here's another believed background to the term 'Chav' - Apparantly derived from the term 'Cheltenham Average' used by locals to describe the 'youths' (I use that term loosly) that used to hang around on street corners with their bottles of White Lightning, tins of Special Brew and did all the things generally associated with Chavs. Will we ever discover the hidden legacy behind their branding?!
Should probably point the yanks over to www . urbandictionary . com to look up what Chav means too :)
