The buyer who could afford a 2002 CRV in 2002 is more likely to be the kind of buyer who trades it in in 2008 for the updated body style (and every trade in is an opportunity for the car to be sold overseas).

There's plenty of CRVs and SantaFes on the road but the present market share of the 2002 SantaFe has increased relative to the market share of 2002 CRVs when compared to what the situation was in 2005 or so.

We're obviously talking at a statistical, not individual level here. Of course not only wealthy people buy Hondas, just more wealthy people buy Hondas than Kias and wealthy people are more likely to trade in their old car at a dealer which makes it more likely to wind up overseas (if it's got too many miles to easily resell in the US).
