Cybertron Downshift Question

[Mega-Prime 316]

Hey guys, I have been looking at my Cybertron Downshift in car mode and I was wondering what car he is based off of. Can you guys ID the car? Also what other colors might look cool on that mold, other than black? Any suggestions?
Thanks

Looks like an old school Charger to me. Like a 68.

He's a mash up of a few different cars so Hasbro didn't have to shell out a licensing fee.

Front & Rear End: 67' Barracuda

Roof: 78 Challenger

Sides: a blend of the Cuda and Challenger.
