i dunno but im thinking if a domestic guy is getting into imports he'd probly build an old school import like a datsun 500 or an old school rx7.
The old school imports were very similar to the smaller muscle cars of the 70s. Plus the old cars don't have as many electrical things to do deal with and it would be easier to switch to something around the same as a domestic or even simpler. Plus older import engine were carberuted and usually had a deeper groan than the b16's of today ^_^
Thats for a really hardcore domestic guys most of the domestic guy's dont have problems getting used to it, some guy on supraforums switched from a roush mustang to a supra and he seemed quite enthusiastic so basically it boils down to there bias, that will determine what kind of car they would look for in the import market.
Again just my opinion could be totally wrong ^_^
