Do not use this car hire firm!! Booked online on a uk comparison site! We had in fact rented a car for 1 day then a bigger car for a further 10. The first car was filthy the vents were broken and the radio didn't work. Marrakech then had a little heat wave and with a 10 week old son we couldn't have a hot car. The second cars vents were full of dust! We turned on the ac to be choked!! They gave us both cars with no petrol and both were unclean. And both cars were not what we ordered!!!
As for deposits.... When I booked BOTH cars (and through 2 different websites) there was NO mention of a deposit. The cars were in my mums name and she was rushed through the paperwork in broken English. She was then charged a deposit of €1,400!!! When we went back the next day to question this they told us she had agreed to it and as honest people we said actually you told us 4000dh to which they denied and said the contract was signed so they wouldn't refund the payment till the car was returned. I paid for the car that was for 1 day and I was over charged by £10 when again queried they said that's not their fault and that's the rate.... The rate I was given was less and I also paid a small holding deposit to guarantee it. Still got no where!! Absolute robbers!! Go with Hertz or someone more reputable because you get much nicer cars and much better service!
