i'd rather the E30 - for £500 there are better cars suited to the track, and imo, a 924 isnt one of them. I would want something that had some performance on a track day!
theres plenty of E30 320's, a few 325's and even an E34 535i Auto Sport for £349!!
Automatic, 140,000 miles, Brilliant Red. Full M-Tec Body Kit, Alloys, Recaros, Electric Sunroof, Traction Control, M-Tec Steering Wheel, AC Schnicher Exhaust, Etc. Trade Sale No Tax Or MOT, Body Work Very Clean, Can Be Heard Running, Drives. Faulty Idle Speed Control Valve. No Dreamers Or Offers. £349.
Bargain!
