I'm probably selling my R32 in a few months and am looking at getting a Coupe. The BMWs seem great value for money, especially the 135i. My preference would be for an Audi, A5 or TTs, but they are significantly more expensive than the BMWs.

I actually haven't driven either, has anyone driven an M3 and/or 135i and are able to give a comparison. I'm looking at 2005 E46s and near new 135is, so looking at spending around 70/80k. Oh and I need 4 seats, otherwise I'd get the 370z
