There’s a certain allure to a car with two doors. It says I’m free of encumbrances, my responsibilities are few, I can afford to have something just for me, and most of all I love to have fun. Why? Because when it comes to practicality, coupes have a tendency to come up short. On the other hand, most of the best coupes under $30,000 handle brilliantly, many have more power than they really need, and they are attractively styled. While a Coupe may imply you have yet to grow up, it makes you very glad you have.
