Museums in Germany
The 'Berg & Tal' adventure resort between Hamburg and Hanover is best known for its huge Snow Dome, which is visible even from the highway. Naturally a lot of additional tourist attractions await visitors. These include a go-kart track, a hotel, a restaurant and a model railway.
Also there is a small car museum which opens from the model railway display. There are about two dozen cars shown, with Mercedes being the most represented brand, but there's also a Triumph from 1949.
Small, but nice local collection of classic cars, including a Porsche 718 RSK
The Engstingen museum has a nice collection of about 140 classic cars, made between 1945-1959. Additionally there are photos, posters and a recreated workshop
This museum was opened in Spring, 2017 featuring "interesting exhibits and scenes from almost every decade" but focusing on the period between the 1960s and 1980s, including the VW Golf GTi, Opel Manta, Porsche Targa etc.
