Don't bother with the stolen one, there's plenty to choose from. As for too cheap, prices dropped hard if you wanted to sell. I let mine go at the end of 2010 for a lot less than I and others though it was worth but you couldn't sell them. That was fully serviced 40k 2006 plate, 1 owner excellent condition too.
What year, mileage and price are the ones you're looking at?
