Yeah I have but I know forum cars are normally well looked after and dealers are overpriced. Constantly looking for cars that have been newly posted on these sites. Just haven't found the right car at the right price yet.
I currently have a Mk5 golf GTTDi and as I'm only 21, I am looking for something a with a little bit more to give!
Dealer cars are certainly overpriced to begin with, but they do come down and you can expect a certain quality finish to the vehicle (if you enforce it).
I have watched a certain black SE currently for sale drop from £16,895 ro £14,795 at a BMW dealer, mind you most of that drop has come quite recently and it is still overpriced in my opinion.
On the other hand, being a great buyers market, feel free to go out there and make offers!
I've been looking for 4 months (for something special same as yourself) and look daily too. Where abouts are you? I shall post some up if I see some..
