We've had 6 between us, from 1.6s, to 1.9s, to an ex Louise Aitken Walker 205 rally car, very similar in spec to Tony's one above.

Depends how mint you want it. I've bought 3 sub £200 to break for spares because of hideous bodywork, and a couple of nice ones at £1200 ish.....

Funnily enough, I ran a 1.9 as a daily driver, and apart from service parts, MOT, an alternator, and tax, it didn't cost me anything else than the £150 I paid for it.

When it got broken into, I bent the door back with a block of wood and kept driving. It sold on Ebay last year for £250!
