James you're very right about replacements though. I've also got a Yaris T sport, great fun and quite economical too. But what I'd get for the money I'd sell it for wouldn't be half as fun...or useful.
The Corrado really does tick several boxes though - rare, stylish, great street presence etc without the constant fear i know i would have were i to have a porsche or aston instead
