you said it yourself - "London"
I live out in the south west corner of wales and mine is £230 - so yep, definately a personal and location thing - best advice I can give you - move house
Wayne370z - welcome - and I agree with every word - particularly the wing mirrors (its a bit of a PITA)
Kev T - have you got a linky to the US site (for piccies etc) - cheers
