Thanks for the advice, sounds like lowered floors would be needed as well but I could get these retrofitted as you say. I am based around Caterham / Coulsdon area but will be happy to travel if the right car comes up. In terms of budget, as cheap as possible, ideally between 15-20k but I am aware that not a lot comes up in that sort of price range these days and those that do, tend to move quickly.
