Easy RentCars cares about their service, Europcar does not.

Avoid like the plauge. They consistently take at least 2 hours to check in, they have no problem telling you "they just had 10 flights land, all behind schedule so there's a sudden rush, it's not usually this bad." They are lying though their teeth, which seems to be a motif for the company. Do not trust anything they say. Get all paperwork duplicated in your native language and above all, do not trust them to be honest. Inspect every tiny detail and take photos of even the smallest cosmetic mar. They look for small ways to rip you off. The bumper with had a broken restraining clip so it wiggles if you pull on it but had no visible damage and needs to be pulled decently hard to see any flex. This tells me that the car was previously damaged, they cleaned it up but did not repair it. Now that they have hard to notice damage, and know where to look, I expect they tell every driver that it is new damage and keep milking it.
