that 650 gran coupe is a monster. got to drive it for a few hours on a business trip in Texas. unfortunately, its the worst car i've ever driven when trying to blow someone off the line. guy pulled up next to me at a light in his mustang, looked at me, revved the engine, i figure, wth, it's not my car...so light turns green...i mash the gas...but have to wait for the f'ing motor to cut back on before it leaves. when it did, i reeled him in quick and blew past him after a couple hundred feet. for a close to 4500lb car, it handles nicely, plenty of power. it looks better than a 5 series too.
