I think you're missing Garrett's point. We prototype junkies tend to buy these things by the dozen and then when we have what we need we stop.
The vesties buy tend to buy the pretty colored one at a time.
So more of the black ones get sold to dealers up front. The colored ones sell but over time. So the maufacturer ends up discounting them to get rid of them.
Time is, of course, money.
I bet if you did a pretty colored car of the month club, well, maybe not by that name, the great vestie rabble would go and subscribe to it with abandon.
Perhaps. Buying the single car as usual I imagine. But...it's not really relevent to speculate on what might happen when data exists with regard to what DID happen. A manufacturer has to develop marketing strategies based on known results as much as possible.
