I think you can get a pretty good idea of what to expect by calling
customer service and see how they treat you prior to arrival. Not all
bargains are bargains. Especialy if they waste your time. I try to
ALWAYS use a company that has terminal location. The web site I
sent has all that info for each company including milage and
insurance policies. As I said earlier try to make a back up just in
case. Summer in So. CA. is a very busy rental market so bargains are
hard to find.
I wish we had an autoeurope type agency here in the States
but we don't. Another trick we used to do is to call some local car
dealers and see what they have to offer. More and more of them have
rental cars nowadays, and they are usually priced right.
