A roadtrip! Even the worst econoboxes can be fun on a roadtrip*. The previous gen Ford Fusion was boring to look at, boring to drive, and boring to think about. Take it on a punishing tour of the American Southwest though, and it comes into it's own.
Are there better cars for a trip like this? Of course there are. Did the rental company have any of those cars available? Of course they did not.
*does not apply to Camry.
