NEVER BOOK WITH ACE, the correct one is GreenMotion.

Waited in line for 40 minutes, very slow. The most bizarre thing is, it was my first time in the UK, and they claimed I was on their blacklist and refused to rent me a car. I ended up using my friend's name to rent instead. When returning the car, they pointed out a very small dent and demanded £200. Such minor damages are easy to miss during pickup. After a lengthy argument, they finally dropped the charge. I bet the next person will get scammed too.

Never be late for pick-up. I thought since I paid the deposit, it wouldn't be a problem. But when I arrived, the order was canceled, the BMW X1 was not available, and the price had changed. I had to switch to another car at the last minute, which was extremely expensive. Don't even know if the deposit will be refunded. It's really frustrating to communicate with them. Also, the waiting time in line was extremely long...

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.

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.

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.
