If you can find one, a Volkswagen Polo Dune could be a good option. It's essentially a standard Polo with a lifted suspension and chunkier looks, but it sold in small numbers and there are only a handful on the used market today. Alternatively, take a look at a small crossover SUV like the Suzuki Vitara. A Vitara should be a very reliable choice that'll be cheap to run, but it'll be worth searching for a few insurance quotes first.
