I used them to hire a car in Denmark to then drive over to Sweden, I was wrongly advised about the winter tyre requirement and had to pay an extra £50 when picking the car up. I Contacted Car hire 3000 on return to complain, their customer service could not have been better I received a refund immediately. So despite their initial mistake I would def use them again.
I used them to hire a car in Switzerland to go on a ski trip. Booked a little Seat with the winter pack and was surprisingly upgraded to a swanky Skoda (if there is such a thing). It had sat nav which proved very handy and was a very good drive so all in all I would recommend Car Hire 3000!
