NEVER BOOK WITH ACE, the correct one is GreenMotion.

Green motion car rental in London is a scam. We booked a vehicle but was upsold to another vehicle , with constant pestering of selling insurance. In the end , we took the cheaper insurance option but they claimed that damage was found and force a claimant of another 200-300 pounds for damage. Utter disgrace company and will never go back again.

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.

Car category I booked was not even available at the location. Told by counter staff go and complain to ACE. Given a completely unsatisfactory vehicle instead.

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.

1.Staff was rude.(Person at desk who's name is Ame,was very rude). 2.Each and Every staff person at desk are trying to force the customers to buy full protection insurance from ACE/GREENMOTION. 3.If the customers have bought the full protection insurance from other website at the time of booking online,they are asking us to call back and cancel that insurance and then buy with them at the desk. If you are not willing to,they would scare you with big numbers,big deposits etc. 4.Only if you buy full protection with them,and they suddenly act to be very kind and be polite to you. 5.Paid shuttle bus should be free as almost all of the rental cars at the airport is free of charge. 6.I had to wait almost for 3 hours to reach the front desk because of long queues and no one even cared if we are ok. 7.It would not take that long, only for the fact that each customer had to go through the same process of staff trying to up-sell their insurance and cancel the already booked insurance.staff are happy even if the customers are waiting outside for hours as long as the person at desk buys the insurance with them etc.
