Sinsheim Technik Museum Germany
If you are interested in tanks, planes, trains, cars, racing cars, bikes, etc and you want to see a running Panther tank ?(put a coin in the machine and it will run) than this is a must see for you. There is really too much to see. The collection was so big that they made a new museum ....the Speyer museum (see below) .
