i used to drive a cadillac, i mean a real boat. had no exhaust south of the cat. 425 cu. in. 7 liter V8, it was loud as hell.
one night i was leaving my wife's, then girlfriend's parents house really late, and i mean really late. so i didnt want her parents to be woken up by the sound of me starting it up. it was parked on the street, at about only a 1 degree grade. i tried with all my might to push that (and i was in the best shape of my life then), and i could only roll it about 10 feet.
needless to say, i think i woke them up that night.
