No problems

The store was busy with many customers when picking up the car. The queue moved quickly, and the process was smooth without any upsell of extra insurance. The Insignia was upgraded to a Passat, which was very new. Everything went smoothly throughout the trip. The staff checked the car thoroughly when returning it at a different location and found no issues. The paperwork was signed quickly. Good experience overall!

I got a downgrade of car type due to my reserved car was not repair yet

I have experienced Europcar before, they advertise a nice car and then usually offer a substantially lower model as the or similar e.g. this year I rented a Kashqai and got a Renault Kajar, last year a Merc E class and got a Volvo V90 and so on, I will try to avoid them in future as its an obvious sales tactic. I upgraded to a Merc C class that was good.
