I rented the 2011 Mustang for three days in LA. The overall qual
impressive, much better than I thought. And the cabin is quiet, too. I think it was better than most sedans in this price range, and it is a sports car. But I did not feel the 300hp of the engine at all. Maybe because the Mustang I rent had only 30 miles on it. The engine was still in the break-in period.
