Just astounding. I had heard about it, and came when I was in the area, but I was still shocked by the amount and diversity of awesome vehicles in here. From the street it doesn't look like much. Nice enough, but small. But then... pull into the free visitor's parking garage, and you'll seen enough odd vehicles there, before you've even paid to get in, that it puts some other museums to shame. There's a small lot just outside, and one in front of the building for "oversize vehicles" (recommended, too, if you have bad knees like me and walking is a pain.) There are charging stations in the garage as well.
I was already impressed and I hadn't even been in the museum. And then, wowed again, repeatedly. So many perfectly preserved (and often driveable) oddities from around the world. Microcars, racecars, planes, sports cars, motorcycles (though really mainly scooters and foldable mini cycles,) a propellor-powered canoe, cars covered with leather or canvas or wood... So. Much. Awesomeness. Plan on at least a couple of hours. They do tours of the basement annex throughout the day, and if I'd had time I would have done that too (probably another hour or two.)
You can walk all around the cars. Please don't touch, and keep a handle on the kids. There is one 2CV you can sit in. I did, of course. Very... wobbly, and tiny. I could see out through the front of the "sunroof." There's a play area upstairs for kids.
Get here. If you love cars, particularly weird cars, it is an essential bucket-list item. If you like history and culture, that works too. There's a little gift shop with tons of toy cars, and interesting books. Oh, and a box in the garage with free (make a small donation please) magazines.
Seriously- check it out. Worth a detour.
