I test drove two different Camaro SS 6-speeds and fell in love instantly. For me, however, only the 1LE would do. And right now the 1LE is only an option on the 1SS. The 2SS 1LE is on the way according to Chevy, so I'm holding out for that.
Here's the summary: the BMW is a sporty luxury car; the Camaro SS is a street legal race car.
If you're into HPDE track days, there's no comparison between the SS and the M235i/240i, tuned or not. Just look how badly the SS 1LE whipped the M2 at last year's C&D Lightning Lap at VIR.
Here's a Camaro6g forum member doing a 2:11 lap at Watkins Glen in his 1LE. For comparison, a lap between 2:20 and 2:25 is considered good for a 2 series according to the tracking forum here.

If you want sporty luxury with the prestigious BMW badge, the 2 Series is your car. If you want a bargain basement race car for the street, it's the Chevy.
