MCGARY

I am looking to go for a p1 before i start spending money tuning my car up. Can anyone put some light on what my car might be worth? £££. I have a sti v5 98, 4 door , silver 27000 miles and with a full subaru service history. Essentially standard exception of hks boost gauge. Scoobysport downpipe ,backbox and a magnex centre. All sti extras. Recently undersealed and wax oiled and window tints. Excellent condition.I am not to fussy to sell but i would rather go for a mint low milage p1. So what do you think???? Cheers
