I really enjoy the ALMS GT class! The teams and cars are diverse, competitive and entertaining.
Its striking to see the size of the M3 versus the significantly lower profiles of the Ferrari, Corvette and Porsche. If we can't have the M3 on the track, it would have been very interesting to see the Z4 GT3 or some variation compete in this class. I would expect it to have outperformed the M3 because of its lower profile and (assumed) superior aero package.
