To a large extent this is going to depend on what you find beautiful.
If you can find one, a Suzuki Kizashi might be your best bet. I am a little concerned about the long-term reliability of its CVT transmission. If you'd be willing to buy one with a manual transmission, you'd have a car that is more fun to drive and less likely to require an expensive repair. A second option is a circa-2010 Ford Fusion or the equivalent Mercury Milan. The Fusion was offered in a Sport trim, though quite possibly this one will be out of your price range. The smaller Ford Focus can also be a very good buy, but I would only get the 2012 or newer with a manual transmission--the dual-clutch automatic is trouble-prone.
