Fake mods
I once heard story about a guy headed to the beach - got up along side a car that had a huge blower sticking out of the hood, oversized chrome wheels, etc, the kind of appearance that just screamed 0-60 in 3 to 4 seconds. When the guy got to the beach this other car happened to be there as well - so he asked the driver of the tricked out car what was under the hood, the driver of the tricked out car openned the hood - and the blower went up with the hood - to reveal a 1.something liter stock 4 cylinder engine with probably 115 horsepower going down hill.
Got me to thinking it would be cool if you could make a fake wheelie bar - made of rubber or plastic or even inflatable that you coudl attach to the back of a car just to fake people out. Of course it would be funnier to put it on a car that did not appear to be capable of needing it.
