Never buy an Italian or British car. There's a good piece of advice for you.

Best advice I ever got...be prepared to walk. If it's not what you want...leave. One of two things will happen, the salesman will make the deal...or they won't and you go somewhere else where they can...

Within reason of course.

This is the best advice that I have gotten. I even had a car for a day and drove it around. I noticed some problems that I did not see until it had been thoroughly cleaned. Brought it back to them, and they would not do anything until I set the keys down on the table (there was a 3 day no questions asked return policy). They paniced when I started to walk away and fixed everything.

If you have a $15, 000 limit I would reccomend getting a new car. I would maybe look at a used passat or accord. They are both four doors and get great gas mileage. They are also both very safe cars.
