Forgive me, as I'm a newbie around here.

I too was shocked to see the car that I wanted is no longer listed but some generic name.

When I called the location directly and asked them, hey, what kind of car is a "Premium Elite Sports Car", they said, "I don't know, do you have a car code"?

A car code?! Ahhhh, now why the heck don't they (Hertz) just have that shown on the website next to the description ?!?

Anyway, I just told him to look up my reservation # and voila, he was able to tell me that it's a Volvo S80.

I also tried it with my upcoming Maui trip because I had no idea what the heck was a Luxury Elite Convertible, it turns out to be a Audi A4 Convertible.

Well guys, so the trick is to go ahead and make the reservation and then call the location and ask them to pull up your file and they can tell you what car it is. If you don't like it, just cancel/change the car type to the one you like.
I know it's a pain in the butt but hopefully Hertz will finally get the drift that they need to keep on top with their website with as much details as possible when it comes to the car. Especially when they start seeing lots of cancellation and then rebooking.

Afterall, for me, that's a major part to why I rent from them because of the selection of higher quality cars compared to other companies.

Hope this helped you guys.
