Don't overlook a nice 123 wagon. They are much simpler to maintain then the ones following. Once set up correctly they will run for decades with minimal maintenance. Personally I'd go for a five speed five cylinder with or without a turbo it can run 80 on the highway with a top end around 100 mph.

The gas powered cars are very nice too and very very rugged but use lots of fuel.
