Ingo and Mary Werk from Los Angeles aren't in Germany to see the usual tourist sights such as churches and castles - they're here to see some cars. Their first stop is the Mercedes Benz Museum, where they admire a collection of vintage wheels before heading off to the Porsche Museum which opened in January 2009. Mary remembers her first VW Beetle, while Ingo stretches his legs in a Porsche 356.
