Fitting the top took a little work, those things fit lousy! But you just gotta fuss with it and fuss with it until you get it close. Close is the best it's gonna get.
There's nothing worth looking at as far as the chassis. Just straight out of the box, painted flat black. I rarely spend any time on the bottom of a model any more. They never get turned over, nothing is ever seen, so why bother.
I also have to plead lazy on the engine. It's straight out of the kit except for the carbs which came from my parts box. I was going to add plug wires and stuff, honest, I really was, but just got lazy and threw it together.
