No hassle and quick release.

They didn't have an economy car available when I arrived and they charged me an additional expense of over $80+ just to drive off. They wouldn't let me have a vehicle without payment. I was very disappointed in this process.

I didn't expect when time for pickup I did to pay extra for mileage even though it say unlimited mileage.

Great. Specifically the price drop protection

Their location is very inconvenient, you have to take a shuttle from LAX to a parking lot then take another shuttle to get to their car rental office. They were very dishonest and unprofessional; I booked a Hyundai Santa Fe or similar SUV (Toyota Rav4 or Nissan Rogue) but they keep insisting that they ran out (very dishonest because there were several available in the parking lot) of those SUVs so they tried to give me the Zeep Wrangler. Save yourself time and do not go with ACE car rental. Very bad service and lots of headaches.

Their shuttle is not at the airport, You wait until you talk to a person on skype for booking, then they say because of delay your car is not there and they give you more expensive one, terrible experience

This rental was definitely a good deal. And the experience was close to an experience with larger, more established rental car companies. But if I may suggest... It was reasonable to specify “no smoking” as the contract was completed and as the car was released. However, to specify the car should be returned in clean condition, “no pet hairs and trash”, made me paranoid the entire time I had the car. I am a fairly neat person, no other rental car company I have dealt with has told me to return the car clean.
