At the end of the day it's a dealer's price, which we all know are always on the expensive side.
Saying that there are cars advertised here on gtr.co.uk by private sellers who seem to want to ask dealer prices too!
Valuation of R32 GTR's is pretty much down to personal opinion, but it's true that something is only worth what someone is prepared to pay!
I suggest you look carefully at adverts of other R32 GTR's and compare with this one to see what you can get for your money.
Selecting an R32 GTR is also a matter of personal taste, some you'll love and some you'll hate.
Good luck.
