Which car should I buy?

Alas my beloved VW Beetle is on her last legs :( so the hunt begins for a new vehicle. I like stylish cars but I also like cheap to run cars. I haven't yet found a car which is both. Anyway, I have narrowed my choice down to a few models. If you have experience with any of the cars, I'd be grateful for your feedback. This car will be a second car, my husband had a Nissan Pathfinder which is the family car. My car will be used for a runaround and for my 20 mile round daily commute to and from work. My shortlist: VW Beetle convertible, Alfa Romeo Giulietta, Fiat 500, Suzuki Swift sport, Nissan Leaf and Audi A3.
