I have the same one, just a different box (I think). I love the model, but was disappointed by it. No engine, just the blower glued to the top of the hood... But the front tires do turn, which is nice. The interior is completely wrong too, another bummer 

I'm doing mine after Max wrecked the front end. After cutting up the front, you have to make a radiator and add a couple of braces. The build was pretty easy, even modding the front. But I think painting it is gonna be a nightmare. I pulled a bunch of screenshots from The Road Warrior and the clay on the car has about 80 shades to it, not to mention the gloss/flat areas of black. I guess I'm going to have to finally learn how to use my airbrush, cause I don't think I can pull it off with a brush  :'(

Can't wait to see yours! Maybe you can inspire me to finish mine  :
