the Los Angeles area Enterprise has about 100 or 150 mile limit, which shouldn't be a problem as I anticipate to stay strictly in the Hollywood area, unless I go to meet my friend for dinner at the Bear Pit BBQ
http://bearpitbbq.com in Mission Hills. (or go to an In-N-Out somewhere near LAX)
the San Francisco location has unlimited miles and I plan to put about 300 to 400 miles on it driving up to Williams, CA and back.
I've had better luck with renting cars an Enterprise than with Hertz in getting a vehicle that I liked, so I'm not too worried about that, I just don't want a total junk.
I do expect to decline extra coverage and use my AMEX card instead.
