I booked a car through Auto Europe for a trip in Slovenia, Croatia and Bosnia. I did not realise that Auto Europe is not registered in the UK and they act only as a "booking agent" who accept your money but do not accept any responsibility. The car was provided by Sur Price in Ljubljana but it came without the "vignette" (mandatory windscreen sticker which confirms that the toll has been paid in advance) although I had made a separate payment for this vignette. I had not realised that the sticker on the windscreen was not the one I was supposed to have by law so I drove until I was stopped by the police and fined EUR 165.00 on the rental worth £50.70. When I complained to Sur Price, they acknowledged that they had made an error but I am yet to see my money. It was interesting to see how they took my money with ease but had no facilities to reimburse me for my loss. So, if you enjoy dealing with dodgy operators, Sur Price must be right for you.
