This 1985 Mercedes-Benz 230TE carries a secret under its hood: A factory gasoline engine. The engine--a 2.3-liter, four-cylinder with 134 horsepower--is a rarity in the U.S. market as most sold here were diesel-equipped. Imported from Germany a few years back, this wagon maintains its European bumpers but has U.S.-spec headlamp assemblies. It's currently listed on Bring a Trailer with no reserve.
