Cars New Fictional Manufacturer

[MactionFaction2015]

Just for fun, I want to make an Australian v8 Supercar on a manufacturer that currently isn't in use in the series. I'll be using Blender for modeling it and I was wondering what visual components that are part of a v8 Supercar, make it that?

They don't really use anything from the stock vehicle at this point (see for example 4 door sedan mustang) it's just a common tubeframe design and v8.
