Well, it's been quite a while since I've weighed in on anything here... But I can guarantee there are no owners yet. There are currently only 3 in Canada, and the keys to all of them are on my desk.

As far as the shift action goes, this is my own opinion, so take it with a grain of your favourite sodium-based product: the lever has a nice heft to it, a clean shift action, and positive engagement. It feels substantial due to the mechanical linkage, and the gates are spaced right to ensure even fast shifts are easy. The clutch is progressive and grabs in the top half of the pedal - I'd personally prefer it to bite a little lower, but you quickly learn to adjust. Drive mode selection plays a huge role in the manual car because Sport sharpens the throttle quite a bit. For the Canadian cars, the manual also has a noticeably lighter-feeling front end, as it's the only version offered in RWD.
I won't go so far as to say the gearbox deserves a spot in the same breath as industry legends like the S2000 or Miata, but it's a very slick unit and certainly far above average. I'd definitely rank it over the 6MT offered in the BMW 3-series.
