Does anybody know if any of the previous 8 cyl and 12 cyl Ferraris of the same year started to have the same value after only a year or two as is the case of the 550 and the 360? Do you think the reason for this is that the performance is basically equal with the more sporting nod going to the 360 or because the 550 styling is way toned down from the 360? It seems to me that in the case of the 308 and the boxer, performance wasn't close and the same goes for the 328 and the Testarossa. The 355 and the 550 overlapped a bit but still a large spread in performance. Now the 360 and the 550 are pretty well matched and it seems in the used market, people aren't willing to pay any difference for it. Hope they step it up a bit for the new 12's so they give a little more for the extra money.
