Disappointed to receive a bill for a crack to the windscreen. Horrified to find they have charged nearly £700.

All worked well.

friendly and efficient staff

Car was excellent and though small was ideal for 2 people. Long wait at pickup for an hour because of long queue. Several people arrived at the same time.

Easy to book, good price and got a discount online with the app. Clear information given so we didn’t have to buy extras.

Yes, it took long to get to GM as they didn't pickup the phone. We ended up calling through airport info desk. It worked then. Then at GM we had to wait in line...not too bad but yes it took that much time (like 45 min-1 hour)

The price drop protector actually works. It is great.

Like: We didn't have to wait in line, either for pickup or drop off. The price of the rental was very reasonable. We were given a free upgrade to a larger yet still fuel efficient vehicle, and the car had GPS, which would have cost us substantially more than the total price of the rental if we had to pay for it.
Dislike: Although you can pick up or drop off your car between 06:00 and 22:00 at their Heathrow Airport location, you can only call them (or any other Green Motion office) between 09:00 and 17:00. Also, we had to pay 9 pounds each for my wife and me to ride the Hoppa Bus from Heathrow to Green Motion and back again. While the car rental broker company, EasyRent, said that we would not be reimbursed for this fee, the supplier, Green Motion, said that we would, and we have not yet resolved this issue.
