The original Porsche museum opened in 1976 in a side-road near the Porsche factory. It was a relatively small works museum with little parking space and it was only big enough to hold around 20 exhibits (in rotation). Porsche built the museum as a kind of "rolling museum" with rotating exhibits from a stock of 300 restored cars, many in pristine condition and still in full driving order. The current Porsche Museum opened on January 29, 2009.
