I have one here that I built years ago. Michaels had it on a sidewalk sale for only 10.00! There's a bunch of working features! The front bogie steers, all suspensions articulate, the missile cradle raises and lowers, landing gear on the trailer raises and lowers and the cab doors open. The only thing I have left to do on mine is put the decals on, if they're still good? I'll probably start watching for a new set. It's a really cool model and was really fun to build!
