I wonder if it's the same car that was being advertised on e-bay a couple of years ago? There won't be many about, so possibly it is.

Opinion was divided at the time on the forum on whether it was nice or nasty. I think the interior is a bit of a Marmite; I like Marmite, but really not keen on those seats!

Be interesting to know what price the car in the above link was being advertised at 2 years ago. Forum members at the time were commenting on it being cheap, but at £18k, if it is the same car, I wouldn't describe it as cheap now.
