I'm hoping it's this since I'm considering selling mine:

Mercedes Benz 190e 2.3 16V . Because this is not what your average car thief is expecting:

Real world mileage is about 22mpg in mixed driving. Not terrible for such a fun car.

I actually have one of these. I was using it as a daily driver for a long time, but I finally decided it needed a break. It really is an amazingly fun car to drive... once you get used to the dogleg first gear. The first time out is a little interesting.

Austin Gipsy. Because, well, it's an Austin Gipsy.
