The WRX sells well in UK. It's a fast car, thats designed to handle around the (tight) UK roads. If you like 4 wheel drifting at 100 and using the feedback to control the car your going to love it.
However if your stuck in America with straight roads, and daft speed limits, I hardly think it's worth it.
When I drove in florida last year the hire company gave me a Dodge Intrepid. It's a good job the roads were like they were else I would have crashed it!
