I keep hoping that BMW will bring the 123D coupe over to the USA, I know they are slowly introducing more diesels (and so are most of the other manufacturers) so am keeping my fingers crossed.
I imagine it would make an ideal commuter car, but also a great back road blast as well.
As an alternative diesel HH how about the new Imprezza with the rumoured 200bhp? With 4wd and reasonably low weight it should be a good b-road competitor to the 123d hatch or coupe.
The one I saw was silver and it really looks good on it - current BMW coupés are at their peak IMO, the 1, 3 and 6 Series coupés all looks great, and the Z4 coupé, saw one of those yesterday too. I never liked the hatch version of the 1 Series, the cabrio looks weird, but the coupé is spot on.
