I must be missing the odd part(?)
I don't follow the exotic market closely, but these cars seem to be still tens of thousands below true value. Of course there is an unlimited supply of people willing to pay ~$136k for a 2003 Modena, they sell for probably $180k new!!
It may have changed, but two years ago, a 360 coupe/U.S. car/no waiting was ~$70k
over sticker. 
3 yr. old Ferraris w/ normal low miles, (practically
all Ferraris have super-low miles), sell for tens of thousands over MSRP of a new car. It is a completely different market, and I'm sure that it is as healthy as ever.
