^^^ he's right...
Anybody wondering what any car's rpm's are for any given speed, simply take how many mph that gear reaches at red-line, then divide rpm by speed. Now simply multiply that number by new speed. example: 8000 divide by 205 = 39.02439. X 161 = 6282.9267. so assuming(dont know) the M5 redlines at 205, it'll be revving almost 6300 rpm at 160. or as in my previous example, at 80mph, about 3150 = slightly more rpm's than my 4-banger Grand-Am. which is at 3100(approx)
FWD on a Monte Carlo? most people don't care? yes thats true.
RWD on a Monte Carlo? most people won't care, but it'll attract enthusiasts? true, but it will scare away some buyers who (would) now see it as a sports car.
GM will be better off making a Camaro again, then they've once again got it for all, with the added addition of a RWD sedan, that they should make only one of, be it the Impala, Monte Carlo, whatever, they should have one.
