It all depends on what sort of car you are after and what you want to do with it.
Immaculate low mileage, 1 to 2 owner cars with complete documented history and maintainence, then expect to pay between £10k to £12k.
Good condition examples with 3 or 4 owners, average miles for age and a history of maintainence, then you're looking £7-9K.
Poor to average condition, high milers (80k plus) with possible incomplete history, then you're looking £5-7k.
There are also examples that have less miles than a few years ago, and quite a few with undeclared damage history...all waiting to catch out the unwary.
All that said, some people get desperate and sell nice ones for peanuts! If you get one like that, count yourself lucky
