I give you the TVR Cerbera.
http://www.pistonheads.com/sales/4151914.htm
30k on the clocks, taxed and tested till spring next year, under £10k
1. Driving dynamics / enjoyment when driving at 10/10ths - 10/10. rwd, no traction control, silly power, silly lightweight.
2. running costs (not including fuel) - 7/10
3. Engine performance - 11-12 out of 10, easy. its a TVR V8 for peats sake!
5. looks - maybe a conservative 15/10? again, its a TVR
4. Practicality - 10/10... 4 seats, boot, many cows gave their hides to furnish it, and it'll annihilate anything in a this side of a supercar in a straight line
