Easily the most impressive Toyota collection you'll ever see.
Housed in what appears to be a bunker in Cologne, Germany, there is a collection of Toyota racing and high performance concept cars built by TMG. The collection is something of a history lesson, with some of the amazing all-time greats from Toyota's racing past, as well as several cars which were developed but never used. So even if you've got Toyota's motorsport history memorized, you're likely to learn something. Quite a lot of the collection is rally cars, but then Toyota was good at rallying.
The oldest cars only date back to the Seventies, but it is quite an extensive collection nonetheless, one which covers a lot of different types of cars.
