Things are a little bit simpler with the coupe. but from a spotting perspective, about the only thing you're going to be able to determine is whether you're looking at a 4-cylinder or a V6. Basically, there are two wheel designs. 4-cylinder models are all fitted with 17" Alloy wheels while V6's get a set of 10-spoke 18's. Additional 4-cylinder traits include body-colored door handles and a single exhaust outlet. V6 models wear chrome door handles, dual exhaust outlets, standard foglights, and a body colored rear decklid spoiler.

V6 6MT or 5AT?
While it's pretty easy to tell that you're looking at a V6 coupe, unless we're missing something obvious, this year there seems to be no clear exterior distinction between 6MT and 5AT models.
