It wasn't Buchbinder (they were bought by Europcar?). Be careful in the return process because they will "find" you an invisible scratch that you will never be able to trace (like under the baggage hood) to charge you for handling and fixing fees.

Anything was perfect.

They kept saying they couldn't process my old-fashioned credit card and forced us to buy their additional insurance, costing an extra 81 euros. What's the point of buying insurance from the rental platform then?

The rental company is Global Drive.

We reserved a BMW X5 but they didn't have any available. They asked us to choose between an X4 and a manual Ford. The X4's trunk was too small and we specifically requested an automatic, so why would they offer us a manual? After we requested a free upgrade, they finally provided us with a 9-seater Mercedes bus. Within two days, the display showed an AdBlue alert, which confused us! Later, in Prague, our car window was smashed, and we couldn't reach customer service. They only have rental points in Germany. After much hassle, we exchanged the car at Munich airport for a smaller 7-seater Mercedes, which soon displayed an oil level warning. Absolutely terrible experience! I strongly advise against renting from this company. So many bad experiences!

The Mercedes Viano we originally requested was swapped for a Volkswagen Multivan. It drives like a bus, incredibly noisy and has horrible sound insulation! It's extremely uncomfortable to sit in. The front layout is like a truck with a two-seater next to the driver's seat, and the rear seats cannot be adjusted. There's no storage space at all, and we couldn’t even figure out where to put a cup of water. They claimed it was an upgrade, which is ridiculous! I will never use this rental company again. We spent over 10,000 on this trip and were expecting the comfort of a Mercedes, but ended up with nothing! Terrible!
