I have a 451 model. They list for $55 in the smart collection catalog. $43 was the best I could get (dealer cost). Anyway, the doors and tailgate/hatch open. The hood looks like it opens, but I couldn't get it open. At one point, I popped the painted hood piece off and saw a black plastic piece underneath that didn't want to move, so I'm going to say that the hood doesn't open.
There is a panoramic roof in it, though. :-) The roof is molded from a tinted plastic that you can see through (though just barely).
