The 1972 Collins ‘Crusader’ Type-II Ambulance – or ‘Boo Boo Bus’ – was Ford Econoline-based ambulance produced for domestic use by America’s emergency services.

We love humble, useful vehicles like this here at The Lego Car Blog, and this one has been built beautifully by regular bloggee 1saac W. of Flickr. Everything is LEGO, including the decals used to create the window frame and (parts of) the red stripe, and there’s more to see of 1saac’s Boo Boo build at his photostream.
