I absolutely agree, completely overpriced. I'm afraid I am very, very much a realist. I paid £14995 for my own car as a 'brand new' delivery miles only car in 2010 (59 plate) which was already two years old. The car was built in May 2008 and is six years old this may. Full authorised Cadillac service history x 4, including cambelt/waterpump/drive belt change (at a Fiat independent specialist) and I'd be lucky if anyone would give me £5k for it. That is precisely the reason why I intend keeping the car for years. Look after it and hopefully it will serve me well. My own BLS is by far the best car I've ever owned. Mechanically cheap to service with an abundance of genuine GM/Fiat/Saab parts. I still smile every time I plant my right foot on the gas! it rockets away on the Shell Nitro diesel and still gives me good mpg.
I'd be surprised if they ever sold that car they're flogging for that price, but then again, someone may just part with the cash!
