Green Motion Car Hire claims to not cost the Earth, possibly so, but it costs the customer dearly!
I rented a car from Green Motion, Manchester Airport over the Christmas holidays, paid up front, and then was told on arrival I had to pay a further 750 pounds seciurity deposit. I returned the car in good order, at 8am in the morning, left the keys in the deposit box as their office only opened at 9am. On returning to Australia, I checked my credit card account to find only 117 pounds returned. When I questioned this I was told there were 2 scratches on the car. They have shown me no proof of this, and I have now been dealing with head office for over a month. Seems lots of other customers have had similar experiences - check out the multitude of reviews on the web. Please be very careful - stick with the respected companies who show customers and the planet some respect! A very disattisfied punter Down Under :(
