"Since I've retired about a year ago, I've built over 30 lego sets. All but this one have been FANTASTIC. Those include Tower Bridge, all of the arch series and several of the modular buildings. Oh, yes, I find Lego a nice, relaxing hobby and give some of the sets away to kids. Back to this one, I agree fully with Zibbit. Every company has a dud, clunker, lemon....and from my experience the VW van, it's Lego's. The roof structure is very unstable. Some Lego sets are challenging....and thats a good thing. this one was just plain frustrating. With that said, Zibbit, Lego is a great company with great products and customer service. Buy some other Lego sets, you won't be disappointed!"
