I've rented from Fox in both LV and in Orlando and have always been satisfied. I even had a time when there was a nick on the windshield when I brought it back. Since I never take their insurance, I figured I (or more accurately, my insurance company and/or credit card company) would be on the hook for a few hundred dollars, but when I called them, they told me their glass repair company had been able to seal up the nick and there would be no charge.
That having been said, because of the extra shuttle ride, I will only rent from them if they're at least $15 cheaper than the companies at the main rental terminal.
