I use green motion seven or eight times a year and have yet to get the car I actually book, but it’s always near new and usually in pristine condition. It can be a bit slow on pickup and they can be super picky with condition on return. I’ve definitely been the cause of a scratch to two in the past, but there’s been at least one occasion where I’ve been charged for damage that I halve definitely not caused, which was barely perceptible and so missed on initial inspection. My advice is to be super picky with anything before driving away.
