Just be extra careful mate, plenty of scamms going about with car sales.
A guy where i work bought an Audi TT only to have it taken away by the police because it had been stolen and cloned to an exact same TT.
Funny thing was that the guy that sold him the car had access to a house in Birmingham that actually was not his house but had managed to get the house keys (stolen) while the owner was out, my mate was told to be at the address at a certain time to do the deal. All the paperwork was actually asigned to that address as well
My advice would be to buy from a dealer. If you go the private route, make sure you get HPI checks AA inspections etc. Take NO chances
It may appear to be an honest sale, but you never know who is the owner of the car.
Pay your money and take your chances.
Dealer dealer dealer all the way......
Unless you buy from the forum....then you know you will be getting a well looked after car.
