I booked a Ford Fiesta or similar, but got a Kia Picanto. In my opinon this is a smaller class of car. the instructions said their was a hopper bus from T5. i was unable to find one, rang the hotel to confirm which bus, only to be advised there was no hopper bus from T5 and that I would need to catch the free bus to T4 and then get a hopper bus. After flying for 24 hours this wasn't want I wanted to hear or do, so I caught an uber which was an unexpected expense. The wait time to pick up up the car was terrible, long queue, must haev taken almost an hour. Got hit with a GBP270 repair bill for a scratch on the bottom of the bumper, that really topped of my hire expereince.

The longest wait and an error on my part cost me 4 times the original quote but there was no compromise on their part.

The car was through Green Motion, not Ace. (Maybe they were bought out? I don't know but we were at the right place and they took the rental papers.) Because we didn't opt for the additional insurance that they were trying to sell us or anything else that they were trying to nickel and dime us with, we had to put a £1250 deposit on the car. Fortunately, we can afford that and our credit card limit is high enough to put that much money on it. Many people can't. They told us the car was in good shape with no defects. However, when we inspected the car, both passenger side wheels had "curb rash", and there were a few other scratches. We had the rental agent notate that on our rental agreement. We also took photos and a video. Upon returning, the inspector immediately looked at the curb rash and was going to mark that on our rental agreement when he noticed it was already there. Thank heaven, we were proactive. I will never, ever, ever rent a car with Green Motion.

The ACE is not the real agency, but Green Motion, this resulted in an internal problem that made me wait more than 3 hours to get the car. I would never again choose this agency because of this, which should even be said before booking.

Waited ages to pick up car. Wouldn't accept my credit card for the deposit, but would accept it to pay the 0 excess charges as a result. Car was good though.
