Are you looking at it because you've always wanted one or as some sort of investment? A Paul Smart 1000 would be a better investment than the Mike Hailwood bike.
It's hard to predict ahead of time which Ducati is going to be in high demand. A 1993 Ducati Superlight is worth more than a 1993 888 SPO Superbike, for example, even though there were a lot more of the former than the latter. And the 1993 and 1994 888 is worth more than the 1994 916 that totally killed the 888 sales. Ducati brought over 200 of the 1994 bikes, sold less than 80 and sent the rest back to Italy to be turned into a slightly different model.
Still, to me $13K sounds a bit high for an MH900e.
