Considering how many 3 series BMW sells in the US, it would make sense to make the 1 and 3 series here. The weakness of the dollar would make them more competitive to say, the G37's, and would help out with the cost to export markets too. Probably won't happen, as that would take to many jobs from the Fatherland though.
Would be nice if the 135i/335i didn't start at 35k/40k . . .
On a side note, Automobile Magazine did a comparison of the 335xi and the STI and EVO X. Considering that it makes do with brake actuated stability control and open diffs, the 3 did really well. Make a 335xi CSL, with real diffs, and things could get interesting
