Craigslist is always chock-full of car goof hilarity! Some of my faves:
"New cadillac converters"
"Original miles" -what, as opposed to replacement miles?!?
"12 volt rear end"
"ready to restore" -lololol
"ready for paint" -just dusted with rattle-can primer
"Rare"
"Camero"
"Heathers" -did you mean 'headers'?
"Mustang, built in late '65, registered as a '66" -maybe he's too young to remember the new cars coming out in September or so....
"Cummings diesel"
"stall converter"
"posse rear" -round 'em up!
I'm sure there's a bunch more that I'm not thinking of right now....
