The service speed on-site is fine, but if you deviate from your reservation plan, the staff might overcharge you, and you will need to haggle in person. However, the shuttle bus service at Los Angeles airport is insufficient. We waited over 30 minutes for a shuttle, and it was just a minibus. Other rental companies use larger buses that arrive every 3-5 minutes. I probably won't rent from Advantage or EZ at Los Angeles airport again.

The line for picking up the car was way too long. I had an appointment to pick up the car at 9:40 PM, but I didn't get it until 1 AM, wasting an entire day's rental fee. The airport shuttle is also very scarce compared to other rental companies that have shuttles every 10 minutes. We waited for an hour before one came.

Very rude counter staff at LAX. Not helpful at all, pressure selling insurances and other products

Call center agent at Hongkong helped resolving problem caused by ‘Advantage’ the car rental company at LAX.

Like: Super comfortable performance car. Just drove itself on cruise control and GPS. Very powerful. Felt like a movie star driving down wiggly Lombard Street in SFR with all the tourists running to get a shot of this car coming down. Masses of room in the boot too which was not affected by the hood being down. Easily fits 2 big cases and our small bags.
Dislike: Nothing

Like: They didn't have the car I reserved so I was automatically upgraded.
Dislike: The only I would change would be to have online access to my reservation to make adjustments such as change of pickup time or be able to add a driver.
