I hadn't known "boot" was the word used for trunk in Europe, until reading the many threads that mention carboot sales on this site I thought it was only an Australian word.
We call carboot sales here "group yard sales" which are typically held at churches where I live. Flea markets here are similar, but the only one I ever go to has some sort of covering/roof sort of thing with a building. The Milton, WV flea market has a building along with a covered part where people drive their cars up and sell stuff from. They had a large fire a couple years ago and they had to rebuild most of the building part and it is very nice now (nicer than before, actually). They had a vacuum store in it at one time and I bought an Oreck handheld/canister from it once.
