Years ago I did a revamp on a very tired but basically sound S2a. Bought it for £800 spent about £300 on it and just managed to get £1500 for it. Probably worth £8000 plus now.
Silly
Have a great one, one and all
Ps ideas are interesting and evolving a little. Boxster?...
Most of the suggestions here wont fit in with your £400 budget for tax and insurance, but the Smart Roadster will. My wife's costs £110 to tax and her insurance is well below £200 Car is totally reliable and will outhandle almost all the cars mentioned here
