I like it. And it doesn't have my 'bumpy' lines!
If it looks like a wing, then what sort of lifting forces are we talking about?

*As a 'free-air' body,it would have Cd 0.04
*As a half-body in mirror-image ground proximity it would have Cd 0.08.
*Adding wheels would bump it up to around Cd 0.13
*Adding wheel fairings would lower the Cd.

Are there any posts showing the center of internal volume, lift (center of pressure) or mass based (if based on a FWD car) for the 3D aero-template?
