I rented from Fox at SNA this weekend. The car was pretty beat-up--lots of little scuffs and dings, even missing a hubcap. The brakes squealed. In addition, they seem to be the only rental agency that's off-site; with any of the others, you pick up your car in the garage practically right in the terminal. With Fox, you have to call for the shuttle. For my trouble, I saved $1/day over National. I won't do this again.
