Very wise not wearing a helmet. :wise:
It was sort of what I expected - a totally liveable daily car with some maniac genes hidden in it.
I had not driven an M car before, so unfortunately I can't compare it to anything other than my 135i that I took with me that day. The M2 was in that promo blue color, had a manual gearbox and the optional M Performance exhaust.
The sound is completely wicked for a factory exhaust. It is VERY LOUD with the flaps open, though tame when closed. The piped-in engine sounds suck big time, but with windows down you won't hear anything other than the fully-opened exhaust, hehe. It is a must-have option.
Honestly, it did not feel as fast as others have stated and as I expected. Mine is weaker (326 vs 370 PS, 430 vs 465 Nm), but the thrust, and sensation of acceleration is, surprisingly, on the same level. It pulls noticeably better up top and does not die after 6k rpm as the 135. I definitely do not want more speed and power, though.
The cabin is too dark due to the standard black leather (hate it) and the cheap-looking dry carbon trim. Standard low-tier BMW.
To finally answer your question: the only two other cars I would consider: TT RS and M3 in San Marino Blue. They had this exact spec there and I fell in automotive love.
I'd buy the M2 in a heartbeat because I'm currently 20 (not that like I will in the near future sadly) and like small-ish coupes. I am sure as I grow up I'll be leaving towards more and more to the aforementioned beautiful dark blue M3 with brown leather. :drool:
And by the way... even though the 135i is worse in every objective way... I'd keep it alongside the M2. I can't put my finger on it, it just feels more alive and funky. Yet looks much more understated. Might sound like a cliché, but that's just what I was thinking on my way home.
