doesn't a lot of the amount of available discount depend on factors like how the particular model is selling, how many are in any given dealer's inventory, how long the car you're considering has been on the lot, and how much the dealer wishes to improve his next-year's allocation by moving units?

if a car's been on the lot for 6-8 mos., aren't they going to be more likely to wish to move it? and likewise, if the dealer's anticipating a hot year next year b/c of the new 911, wouldn't their allocation amount/position improve if they sell more cars now? i always thought this stuff had something to do with it, but apparently it's just a factor of waiting until next february when the new caymans start showing up, is it?
