Tazz Kill Er

I'm thinking of changing the classic and getting a newer model year, i have looked on piston heads and there are a lot of cars but they seem to be all over the place value wise.

The car is a 98 v4 turbo 2000 in red
Mileage 160K
4 pot calipers on the front with grooved rotors with DS2500 pads
wrx sliding calipers on the back with vented and grooved rotors and std pads
16" standard wheels
magnex 3.5" round backbox
Some service history, with loads of receipts for all the service items, i like to do the work myself unless its a cambelt which i had done at subaru specialist.
