When we were in Vegas and visiting 3 national parks in June, we realized that much of the Florida rental car fleet have been moved to the Far West. The snowbirds didn't show up in Florida in 2021, but the rental cars did. SUV rentals were running $700+ a week in Vegas.
New car lots are essentially empty of new vehicles right now. Covid shut down components factories and there's a shortage of electronic components. Therefore, rental cars are not being replaced, and the fleet is aging--with more miles on them.
I'm still piggybacking on a Hertz Gold Card from my ex-MegaCorp and get a big discount on rentals. I was paying $425 for a GMC SUV, and felt glad to get it.
Hertz is having a terrible time in Vegas getting anyone to work their rental desks. And big hotel rental agents are only part time--Thur., Friday, Sat. and Sunday. Hertz is also in a reorganization bankruptcy with maybe 4 different rental brands they own. I'm very surprised that rental car rates are dropping.
