We have the wooden elc one. Dd (4.5) plays with it for hours. We have the ELC road track which attaches to the garage. She uses matchbox cars. But she can work the lift and uses her imagination - the cars have names and argue over parking spaces.
Ds (21 mo) also plays with it for hours, shooting the cars down the ramps. We had to tape the ramps onto the garage to stop him pulling them off all the time. And he does just fill the lift shaft up with cars. But it takes 15 minutes to do that and 2 minutes for me to get them out so I think its worth it.
The garage is strong enough for a toddler to stand on, too, which the plastic ones don't tend to be.
