They are my new heros. Although Christine died in June of 2010 of cancer and Otto entered the Mercedes museum in Stuttgart, Gunther is somewhere in Bavaria. I surmise he's debating whether to go with a 3-cylinder Metro or a 1996 Tracker.
Note the similarity.
Otto - Gunther's vehicle

Phoebe - 1996 Geo Tracker 4WD
Without Otto's two-legged peace symbol on the front you'd hardly be able to tell 'em apart.
