if its a nice custom car, like, a badass muscle car or something, i'll throw a peace sign, but usually imports, unless they are incredibly clean or i know them, i won't even look at, because there are too many ricers

but i'm with john, except on the other side, i'll straight up tell the person i really think their car is nice, and if i have a real question i'll ask them, but i won't bother them usually.

and i've only ever gotten one compliment and i stared like an idiot because it was so out of the blue, i just got confused and had a brain fart
