Rob, its BoxSter!
You can get a nice early spec car with some toys and extras for 18-20k. Ropey ones are cheaper, there are loads around so look carefully and find a bargain. I am picking one up tomorrow for a friend that I helped him find.
Black with black leather and hood. 1998 2.5 Tipronic S (YUK!) 62k, lux pack, leather, 18' Sport design wheels (GT3 ones) climate control, Traction control, etc etc. Was up for 20k, got in for £17.5
Cheap to run and a pleasure to own. NOT fast in a straight line but as Oranaco said earlier, thats not what they are about.
