I got to watch some new Cadillac coupe eat a late model vette on the Southwest freeway today. When it went by me like I was standing still, even tho I was pushing 80, the engine in that thing didn't sound like grandma's V8, it sounded like a Formula 1 Ferrari for gods sake. What the hell is in that thing? I would venture a guess that it would give some of my MB's more snarly cousins on this forum a run for the flag.
