Ok, here's what you do:

1. Find LS3 parts car with a good engine and rear end
2. Find an STS-V parts car with a good front end and transmission
3. Swap in LS3, AWD transmission, front and rear ends
4. Do some crazy hard launches with that setup
5. Call it the "Grand Prix G8"

6. When said car runs reliably, laugh in GM's face
