It should be more transparent.

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 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.

ACE London Heathrow branch is actually Greenmotion company which I believe they are partner and Greenmotion run service for the ACE. Therefore the service is similar to Greenmotion. One thing incorrect is I did have to pay for shuttle bus fee, which did not correspond to the voucher mentioned shuttle bus paid.

Like: The Customer Service Advisor Danielle provided excellent service and was very friendly. I would definitely recommend Ace Rent Cars/Green Motion because of her. thank you very much Danielle.
Dislike: Long waiting time to pick up but mainly because customers did not find out about company's policy before collecting car.
