Last weekend, we visited the Louwman Car Museum in the Hague. I really had no idea what to expect of this museum, but I was surprised in a very positive way. The building is new, and filled with cars from the late 1800's till today. Including most (if not all) the classics.
If you're in the vicinity of the Hague, you should visit this museum (even if you're not a petrol-head).
