Yeah, You see a cheap looking one and its usually been ruined with some dodgy mods, is an import, high mileage, automatic or Cad C/D, decent UK GT's with sensible miles seem to still attract high prices, not sure what they sell for though.
I think, if you want something that isnt in the list above, entry level is six grand for most offered.
Wondering what mine is worth, will advertise it when I have accrued enough (non spamming) posts
