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.

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.

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.

Dislike: Even though I booked for automatic car but they gave me manual as they didn’t have automatic at the time of pick up!!
