I'd also initially go with overpriced but then this isn't the first time I've seen a mk1 at this price.... It would have to be in the same condition it left the showroom in to even be considered, and like raferackstraw says, you could buy a what appears to be nice one that end ups displaying plenty of hidden nightmares that end up costing you 000's over time to get to mint again.
However, this to me personally isn't that desirable. It's an early 1800 with factory fitted 1600 wheels. I'd only pay top dollar for an immaculate series 1 swallow tail 1600, or an immaculate roll out Campaign edition 1800.
