Ok, I guess I'm that bored. This is my attempt to list all the cars seen in Avis' fleet, with important notes regarding availability, locale, etc. When I have more time (or am more ambitious), I'll include links to ride reports and manufacturer webpages.

Please feel free to contribute!

This list will be sorted by rental class, then alphabetically.
