I work at a carwash, drying off cars all day long, well, sometimes all day. Jeep Wranglers are pains in the ass because of their lumpiness, and many of my co workers concur. Any big SUV sucks to do, as does any mini van. The worst rims in the world to clean are found on the Audi AllRoad, you'd have to check them out to understand. BMW honeycomb rims are awful too.
