How much do you think i would get for my car if i sold it, cos i am looking to upgrade to a slightly newer one if possible

1992 WRX
143000km (89000 miles)
Full respray 2 months ago
MOT til April 2006
Tax til end of September 2005
New shape front bumper
Prodrive rear spolier
de-locked boot
boost guage
RS Racing back box
Turbo XS dump valve
18" wheels, brand new
Private plate


Also, this could also be classed as sort of an advert to sell this car. I am looking to see how much i would get for it and depending on what people think, i may sell it.

Cheers people
