This lego car gets its name from the fact that it's base is built on jumper plates. That is so there aren't large gaps in-between the wheels and the body. Below the model are the parts for the next step. For your convince there are three parts, the base, the body, and the top.
Step 1: The Base
Step 2: The Body
Step 3: The Top
And your done. Next turn your regular lego car into a regular lego supercar!!!
If you make one skip step 3 and build your own top and post it in the comments!
