I'll admit it--I'm a sucker for Plan toys. They are pricey; however, I appreciate that they are fun, educational and free of the usual chemical garbage that comes with most conventional (plastic) toys. Like all our other Plan playsets, this one is very sturdy and stands up well to the rigors of preschool play.
It is small, to be sure. I've noticed that all of the Plan city series toys are pretty little. However, this doesn't deter my kids from playing with them and it's actually fine with me because the toys don't take over the play room. (Note to Plan: It would be GREAT if you would make the country and city series toys the same size! It's no fun to have the giant farm set next to the teensy airport and parking garage!)
The roof on this one is made with a foam rubber-type material. At first I was concerned that this would be destroyed; however, it has held up quite well. The only possible issue is that the little wooden ramps do come off quite easily. My kids like this; however, if it bothers you, it's easily fixed with a little wood glue.
