Greenspan has spoken. Rates will rise and as with every time that happens for a sustained period, valuable but unnecessary luxuries like exotic vehicles and jewelry and semi rare wines will depreciate. True rarity, as in things that can be counted on ten fingers or less will be least hard hit, but run of the mill type "scarcity" like 399 Enzos, will take a significant hit. My prediction is that as rates rise over the coming months, F50's will drop a couple of hundred thousand first. Enzo's, in very short order will drop under a million dollars. I know this is merely of academic interest to just about every living being on earth, except for the 1,000 or so who have the means and the interest in these cars. F40's are currently selling at less than their original MSRP and they are truly iconic vehicles. The same thing will happen to Enzos (and F50's) once they are over 12 years old. Something about being a teenager that is unattractive to adults. We all love kids until they become obnoxious (around 12). They only become interesting again when they are well into adulthood (over 30). I think the same applies to exotic supercarcars.The only real exception is that very well behaved little english boy MacLaren.
