If the 3-Series is a sports car, then what's a Porsche 911? If the 3-Series is a sports car, then so is a Cadillac ATS, CTS, Lexus IS, Mercedes C-Class, Acura TSX. All sports cars... right?
And I'll largely ignore the trolling re the "Why don't you buy an F30." Just because I stand up for a car doesn't mean I will buy it. Otherwise I'd have to buy lots and lots of cars. Hell, I like all the cars mentioned above.
