This is my mates MY93 WRX, adjustable suspension, front mount intercooler, Blitz DV, 17's, AP 4 pots etc. It's for sale for £5,000.


Another mate of mine obtained a near standard MY93 WRX for just £1500. A bit of care with some polish and it came up lovely. Failed the MOT on the rear fog not working and missing a couple of wheelnuts A hell of a lot of car though for £1500.
