Upgrade The Supercar 3D is a casual arcade game where you move along a track to deck out your car step by step, or rather, obstacle by obstacle. Race through colorful levels, collect upgrades, and customize your ride with new paint, wheels, and body kits as you go. The better your car looks, the better your run gets, and the more your car is worth, so keep building, keep racing, and see if you can cross the finish line in style.
