Beautiful F12 DBK. Congrats!!
The 599 was actually produced in significantly fewer numbers than originally expected (economic downturn)....same was true of the 612. Total production numbers through the 5 year run were fewer than 3700 units. The 458 will be produced in close to triple that production run including spiders when all is said and done. The F12 is a unique car in that the roll out has been slower and also due to significant international demand, US delivered cars have been fewer in number explaining the premium (30K or so over sticker) that dealers are charging even some of their more loyal customers for a car. It is likely that the depreciation curve will follow the 8 cylinder ferraris more closely for the F12 (less steep) although total production numbers will obviously be a determining factor.
As great as the 599 is, the transmission is pretty choppy albeit slightly improved in cars with the HGTE package. By the way, the best way to see where the used ferrari market is going for a particular model is to look at what the cars are selling for in Europe. 599's in "above average"condition are going for the 120-140K range in europe....about 30% lower than what asking prices are in the states.
