I just rented from Enterprise* on Bellanca St. in Inglewood, and saved a lot on taxes and government fees vs. renting "on campus" - at LAX. Here's how it worked:
In line with Enterprise's company-wide practice now, they can pick up and drop off as close to the airport as the Hyatt on Century or the transit center where LAX's parking shuttles meet the city metro buses. I took the "C Lot" airport shuttle, which goes to the transit center. Not knowing then or asking about how close to LAX that that Enterprise is allowed to pick up, I walked to the Burger King. (Unnecessary.) I called and they came and picked me up. Happily. They're a profit center and know what we/they're up to.
On the way back, something funny: I'd asked for a map when I picked up the car. It shows the final directions into "big" Enterprise, which didn't look at all familiar. Before crossing the teeth, I called to get vectored into the Bellanca St. office. Good thing, as they said there would have been a one-way drop charge at the big (airport) depot. @:-)Not a worthwhile experiment if anyone wants to try it. Anyway, I checked the car in and was taken post-haste to the transit center. They did say that they'll pick up/drop off at any hotel, then we take the hotel's shuttle to the airport.
* I have no connection with Enterprise.
