I noticed something interesting... Sometimes cars from Avis' Cool Car collection do not display when the rental date is too far in the future. For example:

If I search for a car in LAS for sometime before 4/16 (as of today), I see options for an Altima Hybrid and a Camaro LT. If I search 4/16 or later, I don't see any Cool Cars listed.

I noticed something similar with LAX, but there, the Cool Cars don't drop off until you start searching for dates in Sept.

Any ideas on this behavior?

Thanks!
