just my opinion i'd be trying to keep the car if it's that good and enjoy it cause unless your prepared to take a bit less than 30k (try 25k) your probably not going to move it ( check out prices, car sales, drive.com' j- spec etc, the arse has fallen out of the market, look at all the stageas for sale ) not a real good time to sell, maybe a collectors car like yours might appreciate if kept in good nick, but if you really have to sell it and want a quick sale get your money back plus a couple of grand,
good luck and i hope you dont have to sell it looks real nice.
