Avoid Green Motion when hiring a car. In my case, Green Motion at Manchester Airport attempted to get me to purchase unnecessary comprehensive car insurance by (a) first stating that they could not release my pre-paid car to me based on none of my three licenses meeting their requirements, then (b) changing that statement to saying they would release the pre-paid car to me only if I purchased their insurance, which cost twice as much as my pre-paid car hire. I refused and walked out. After filing complaints with Green Motion multiple times, Green motion refused to refund my pre-payment, so I filed a complaint with my credit card company, who refunded me the total amount of my pre-payment. Subsequently I've read hundreds of consumer complaints about Green Motion on multiple websites/review sites, as well as newspaper articles that reported on Green Motion's practices.
