Had reservations at MIA and MCO for the same V4-RSAR class and I think that Hertz got a new fleet in.
At MIA got a fully loaded white Camaro 2SS 2019/20 with only 1k miles on the clock. Had sunroof, leather seats, 20" inch wheels and all other bells and whistles.
At MCO got a silver Mustang GT which I think is base model but with leather seats and a variable exhaust, but only with 100 miles on the clock. Found out that was the 2nd rental of the car since it arrived on their lot.
Turned out very satisfied.
