I think anything with 2 doors in a coupe configuration. The number one selling sports car worldwide is the Ford Mustang, which maybe debatable for many, including Mustang fans.

The Crossfire is officially classified as a "sports car", but I think anything from a Miata to a hypercar will be included in that list, assuming it has two doors and classified as a coupe. But then again, would you classify a BMW M3 Sedan as a sports car? It has all the other sporting potentials, except has 4 doors.

Probably need to drill down into that list they put out on what they are counting as sports cars.
