As expected, the BMW 135i coupe that has been displayed at the Chicago Auto Show is the same one that we have seen so far at all the shows across the country. Basically, it's the same Sedona red that is available in all the BMW official brochures.
No other news from here, basically everything stays the same as it announced at the L.A Show. The 135i coupe, 128i coupe and the 128i convertible will be available starting at the end of March.
As a personal opinion: after sitting in the car and adjusting the seat, I can certainly that it has less legroom in the back than the old E46 3-series. My editor is 6'2", so he basically had to move the seat all the way back and therefore, the legroom in the back was minimal to none.
