Ditto, its not worth the risk if you have any doubts what so ever, there have been, and are some cracking examples about at the moment for the sort of money that you are talking about.
Have a look on the for sales section on here and have a search on autotrader or something like that, it will gave you a better idea of the right price at the moment. On a side note, and not wishing to sound biased, looking at cars that are advertised on sites such as this one should gaurantee that the car has been loved and cared for and that you will get good feed back and honest opinion from un-interested paries that may have knowledge of the car from previous shows or meets.
Anyway, welcome to the forum and good hunting, and as soon as you buy one, we want pictures !
