Congrats to the OP!
When I first heard about M135i I also thought, feck, it's ugly as hell but I WANT this more than I want 328i M Sport. Alas, M135i manual is full 10 grand more here in Finland (before options) than a 328i M Sport (before other options). That's to say M135i is about the same money as a bog standard 335i, just shy of 60'000 €. I think it's a bit steep for an ugly duckling, even if it has a heart of gold.
