we all know that there are sleepers in the car world. i had an old rusty escort panel van, blow me to the weeds in my hot twin cam celica many years ago.(i suspect he had a HUGE 2.0L turbo with quiet mufflers) he laughed so hard at the next lights im sure he must have pissed his pants. do they have motor bike sleepers? such as maybe a VESPA with 500-1000cc shoehorned in? i will limit my dumb questions to once a week.
