I have to use a six sided impact socket on half the cars that come in. Like everyone said, get a socket that is just a little too small and hammer it on. Then loosen the bolt off by hand. Once I've broken the bolt loose, I'll take the hammer and tap around the socket until it wiggles it's way off the bolt head. If that doesn't work, I'll take the socket over to the table vice and hammer the bolt out through the hole using a punch. It sounds scary using the socket trick, but it works every time. One time I had a key break because the lug bolt was on so tight. Did the socket trick and it came right off.
