Basically I would say a sleeper is "a vehicle that is a lot faster than most people would expect after casually looking at it".
It can be a clean stock appearing car (or truck) that has some serious balls under the hood, or it can even be a car that looks like shit but goes like stink.
Would you consider a stock looking Z06 and a modded Z06. One has a few mods and the other has a built 427 in it. The one with the built motor is completly stock on the outside. The other one has wheels and lowered a bit They race each other and the stock looking one waxes the modded looking one.
Would you consider that a sleeper Z06?
Or lets say a debagged Camaro Z28 with a single outlet exhaust?

For me, it is a car that looks stock, whether it is in good shape or not, but has quite a bit more going for it in regards to performance.
When I think of the most extreme levels of a sleeper, I think of a car that is usually not associated with anything having to do with speed/performance, but performs like quite the opposite; a vehicle built for performance.

*No matter what I do, I'm still stuck with a 2v
Here is an example: A guy a couple years ago ran around a few of the meets in a purple mid 90s Chevy Beretta with a nice sized turbo. He also had some drag radials out front on the stock wheels. Im sure a few of you know who im talkin about. Let's just say he surprised everyone haha.
If some guy thinks your car is a pos, slow or a combination of these two things in relation to whatever it is that he drives, and you beat him then that's a sleeper car. Usually there's a power adder or engine transplant involved. Can be in many forms.
V6 camaro with a turbo is an example of a sleeper.
Also if you sit on your hand for an hour and then rub one off isn't that also a "sleeper"? No that's a stranger, n/m.
