Collecting the rental car from GreenMotion was a painful and time consuming exercise. The worst experience ever, and I have rented cars all over Europe and the USA. It took over an hour between arriving at the car hire portacabin on Monday 20th July and getting the keys to the rental. The low light was being asked what I did for a living and asking for my National Insurance number (which I did not know) to ascertain if I had any points on my driving license as it would effect my insurance , this despite the fact that I already had Insurance booked through CarJet. We ended the 40 min impasse by me providing my American Driving License. This did the trick so no cares about my driving record in America !! During this whole time I had to listen to the senior staff member (there were only two) berating a customer for not reading the small print and having agitated the customer sufficiently then got on his high horse as the customer had used an expletive in a sentence. This set off alarm bells as did being informed that I should inspect the car carefully for damage before hiring it. You are made to feel like a criminal. We were presented with a leaflet (attached) providing a guide to assist your vehicle inspection. It specifically highlighted the Front Bumper, Wheels, Windscreen, Parking Dents, Tyres and Rear Bumper. The Green Motion Vehicle Check guide did not mention the roof, the undercarriage or indeed the clutch!! Having been given the keys to the rental car we then spent 10 mins looking for it. We found it in a loose gravel surfaced compound next to the car park beyond the car washing area. The car had a fine coating of dust on it (I guess from the loose gravel surface). We inspected the car as best we could based on the vehicle check guide, taking photographs as advised, and could see no obvious damage to concern us. We drove from the Holiday Inn, Jct 4 M4, to Leigh in Kent. The car was parked for 4 days on our drive before driving it back to the Holiday Inn. A 110 mile round trip. On arriving back at the Green Motion portacabin on Thursday 23 July we parked the car. We then went to see a member of staff. The one available, of the two working, was clearly new as he didn’t know anything about the return process. The other member of staff was having to guide him through the process whilst dealing with his own customer. The experienced staff member said he would be out shortly to inspect the car. We thought that everything would be fine until he asked if we had taken photos of the roof. I was stunned as I had never heard of such nonsense. This was before he even started looking at the roof. It was as if he was planting a seed. He then proceed to suggest that we had put scratch marks on the roof. On closer inspection and through the light coating of dust I could discern some individual marks, so insignificant that I would ordinarily not see such items. I felt as if I was being set up by this employee in some form of insurance scam. The marks look like they would have been caused by someone cleaning the car as they were arched as opposed to straight and they were in different parts of the glass roof. Clearly I hadn’t cleaned the car. The only person to have cleaned the car would have been GreenMotion themselves. I was incensed at the suggestion that I had ‘scratched’ the roof. On balance, if GreenMotion had wanted me to check the roof they should have provided a step ladder and preferably a clean surface. I am not tall enough to see the whole roof of the car. The member of staff said he would be passing his assessment to the department that deals with such things and they would decide what to do next. They are trying to charge 530 pounds to my credit card. I will never use GreenMotion ever again after this experience and would urge others by whatever means possible to avoid using them at all costs.
