I'm looking to buy a car for around 14-15k. I'd like it to be a sporty 4 door car and Japanese. Would anyone reccomend a mazda 6? I can get a fully loaded hatchback w/45k miles for about that price. Seems that is the most bang for the buck. Thinking about a WRX as well. Would consider a Legacy GT or TSX but that is a bit too much $$$. Any other ideas?
