This definitely sounds interesting, will add to my list of alternatives if we have extra time, as Sinsheim is not far from Stuttgart.As above plus the 2 technik museums, all types of technology including some amazing cars, planes and even a Russian space shuttle! If you want a bit of comedy take a close look at the cockpit of the Russian copy of Concorde, the electrics are very familiar to anyone who has owned a 1950's type car!
