Sleepers

They definitely can be, all depends how they are done up

I've thought that sleepers were "sleepers" to car guys, not just the general public. You could make the case for the AMG or M cars being sleepers, then, because people who aren't in the know might think that they are regular bimmers or mercs. Sleepers have always been, to me, modified cars. A rusty old car with a blown v8. Twin turboed sedan. There are no factory sleepers. Sleepers aren't meant to fool people. many factory cars can do that. Sleepers need to fool the people that matter- the car guys.

I drove a 2001 Cadillac DeVille. It had the North Star V8 in and holy shit did that thing fly! I loved it when the unassuming Honda Civic would pull up next to me. I'd leave them on the line every time.

I've always thought that someone should make this happen.

i was at a meet and a dumb rusted wrx with plastidip wheels showed up, it looked super shitty, he had put a 2.5 hood on it and took the spoiler off, but when he left he spun all four tires like a built evo
