Little 70's Animation

Pretty cool, I can dig it! My two nitpicks would be add some actual lights to the cop cars and use a few more polygons on the cars. Even a few extra polys would make the curves (wheel arches and whatnot) look a lot better. But overall good job.
What software do you use? Everyone seems to be a big sketchup person these days because it's supposedly easy but I struggle with it and get by better with studio max.
