I think I want a 135i. I'm not sure. They aren't technically accurate, because Tiff claims that the Bimmer has an LSD; it does not. It uses the traction control to create a computer emulated differential that applies brakes to the wheel that is spinning wildly to get power transferred to the other wheel.
My problem is I have "penis envy" when it comes to model lines. I could not buy a Cockster, I mean Cayman, knowing there was a better version out there. Same with the 335i, when the ///M3 is available (though the price differential is higher there). The 135i is the best 1 you can get.
Until they release the ///M or Tii version of that. Some guy @ BMW corporate is quoted, when asked if the Tii would go into production, said "There's always room for improvement."
