The parking garage is 3 levels. There is an elevator, 2 gas pumps, oil changing station, 3 cars (although most Matchbox cars and even those that are a bit bigger will fit fine!) and a car wash. Everything is in near perfect shape. Never played with outside or in water. Includes 6 white barriers (they stick in the small holes on the roads), 11 road signs, 24 sections of road that can be arranged in all sorts of ways. The road sticks together like the wooden Thomas or Brio train tracks. The only problem with the set is a few of the white stripes on the road have come off (they are stickers) from so much traffic! I think you can get a new set of stickers from Wader.
