10: Subaru WRX
The WRX was, at one point, one of the most impressive cars on the road, but in recent years the car has become quite dated. Gone are the unique design elements that made the car popular from the start. Instead, we have an almost decade-old design (via Electrifying).
The WRX seems to be living on the laurels of its reputation alone, which is not what most automakers want to have to happen. Time will tell if Subaru will finally update the WRX or if the clock is running out for the storied car.
