Waiting in line to get the car wasn't a problem, but when I said I didn't want to buy collision damage insurance, their attitude turned a bit sour. They kept persuading us to buy various extras, which we didn't appreciate.

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.

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.

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.
