Hello Jimmy..............just because one individual at an auction decides to pay some silly price for a 575 SuperAmerica with manual gearbox, does that mean it's now the market price?............................
Gianni, when this Easter Sunday, a buyer and a seller agree on the price for a piece of property, any piece of property, and conclude the purchase/sale, that is the very definition of 'the market'. For that particular piece of property and those two people - on Easter Sunday 2017. Your question illustrates my pointy exactly. At that auction on that day the market for that manual transmission 575 SuperAmerica was that 'silly' price. Except for those two 'market' participants, it wasn't silly, it was the market. And because it was an auction, on that day there was at least one other buyer for whom the market was his last unsuccessful bid.
P.S. the current Ferrari Market Letter lists 18 550's for sale, a few around and just above $100K and a few a little under $200K (one over) and 9 575M's most around mid-$150's except for three pedals that are above $200K
Yes, there is such a thing as a 'general market' - the notion that for many people interested generally in a certain type of property there is a sense of what the market ought to be for an undefined specimen. Eight to ten months ago you couldn't find a 550 Maranello offered for sale, except in one of the high-end auctions and then for crazy-high estimates. A very few sold at auction at high numbers, well above $200K. The dealers thought that there were lots of buyers lusting for three-pedal Maranellos and were quietly buying more and holding the cars they had off the market.
Right now eBay alone has ten 550s on offer, not a single one asking $200K or more. The asking prices range from $199,899 down to $108,500 for a '97 giallo modena/nero with 45,606 miles. Why are those 550s not selling? The 'market' of 18 months ago is not the 'market' today. You want a three-pedal Maranello? Now is the time to buy. Go see one of those dealers. I'll bet you can negotiate a VERY attractive price.
