I'm guessing that Perrys aren't advertising the fact that you have had issues with it, and hence the person who would buy it would be anyone looking for a nearly-new car for a bit of a saving off the new price.
The fact that you made a facebook fan page about the Twinair Panda, means that you must have been taken in by the car pretty well to start off with. Anyone looking for a similar car will probably also think it looks cool, and thanks to the gunmetal wheels and colour combination, it will appeal to many people.
