Thanks for the details.
I agree that the GTO is an excellent vehicle. It is lamentable GM couldn't equal it at home. It is just doesn't have stand-out good looks (which I know is subjective).
After spending the bucks to engineer the excellent rear wheel drive Cadillac chassis, why not use them for selected other vehicles? An Pontiac, etc.
Mercedes' previous "E series" is the basis for Chrysler-Dodge cars; Chrysler 300 and Dodge Magnum. Slap American style sheetmetal on a first rate chassis, and give it real power.
GM simply stands almost dead in their tracks, while the competition builds and SELLS Chrysler 300s and Ford Mustangs.
I agree with your comments on Nissan.
In my area, the kids get Honda Civic 2 door coupes, Subaru WRI/STX, etc. and hot-rod with them.
If I had a contribution, it would be a mid-sized Chevy Nomad wagon built on a Cadillac chassis. Two and four door versions, V6 and V8 power, and AWD option. Sunroof, leather, Nav, Satellite, touch-shift A/T.
If it had retro-classic styling, it would sell big, the world-over.
I have heard several comments about RWD - why is it so much better than FWD?
I don't know much about the two.
I like it. It is understated, like GTOs from '64-'67. It was, back then, a derivative of the Tempest/LeMans. So for the sake of continuity, it bears a resemblance to the current Grand Prix. Were I in the market for a sedan, I'd be tempted to look in the new Goat's direction.
