35,000 Cars is still chicken feed in the real world of auto production. They would have to crank the number up over 100,000 to make any real money. That's over 400 per day production. Ain't gonna happen. A couple of our plants build 1200-1500 units per day, and we are very small in the industry.
The other part is clear. Horses add weight. You can't make a 500+ hp car that weighs unders 3000 lbs without serious drawbacks. There is no such car today, and IF GM could pull it off, I would applaud them and probably buy one. Again, it ain't gonna happen. The Enzo has a complete carbon fiber tub. No frame. It's as light (and expensive) as you can possibly go in a street legal, semi-mass produced car. Yes, I'll buy the arguement that you CAN make a car with the HP and weight in question, but it would not come from a major carmaker. Like I said, the sounds, ride, and refinement would be so harsh, it would only be good for a racetrack. The comp coupe is a great example. The ALL ALUMINUM Ford GT is another.
