Just finished a rental at LAX with mixed opinions.
Rented a Mercedes C300 convertible for $40/day for a weekend up in Santa Barbara / Santa Ynez Valley. Fantastic rate...other agencies were $50+ for the more-common convertibles like Mustangs, Buicks, etc. Anything in the Benz/BMW category was $100+ elsewhere...or unavailable.
We got lucky on the bus: walked out of T1 and straight onto the bus. At the rental facility, however, it was chaos. I had completed all of the online check-in requirements and was expecting to simply show ID, grab my keys, and go. But no - no matter what, you must stand in line with everyone else. The line moves slowly because they're pitching upgrades, insurance, prepaid fuel, etc. to everyone. Finally, after 12-15 minutes, I have my paperwork and have to walk outside to get into *another* line - this one for the guy who actually orders the cars to be brought up. They were still cleaning my Mercedes, so it was another 15 minutes. As I was waiting, I observed two different customers who had just returned cars arguing about different things - one about a door ding and the other about whether the guy had smoked in the car. (Sixt said he did, the guy denied it.) Without knowing who was right or wrong about either case, it was obvious this was going to be one of those places where there's a battle at return-time.
The rental itself was great...fun car to have for $40/day and perfect weather all weekend for it.
Return was a super-detailed walkaround, with the return agent noting every tiny scratch. Fortunately I'd done my own walkaround before the rental so I knew where the scratches were - my only minor mistake was that the notes in the rental agreement weren't clear about which side one of the scratches was on, and I didn't make them clarify it ahead of time. But since the total number of little scratches matched the total noted on the original rental agreement, she closed out the rental with no further charges. It just took a little bit of discussion to get to that point.
Wait for a bus back to LAX was only a couple minutes.
In conclusion, the only way I'd go back to this location is for a crazy-cheap rate on a high-end car. They seem to rent a lot of Mercedes, Jags, etc. out of this location, so if you want to drive something fun for a fraction of what Hertz typically charges for their Prestige cars, it might be worth it. But I'd *never* rent a basic midsize/full-size type car here - the act of waiting in the lines kills off any value you get in the form of a slightly lower rate.
