3 door is certainly better. Annoying how Australia tends to get only the 5 door variants of hot hatches thesedays. The Audi S3 (now superceded) the Golf R and now the M135i are all 5 door only in this country.
I suspect the S3 and Golf R were due to VW wishing to make the 3 door Scirocco stand apart. Odd though how the Golf GTi is available in a 3 door however.
Maybe BMW are doing similar so they can create an 'articifial' opening for the 2 series later on?
