Great

I booked a Mercedes A-Class, but upon arrival, they said it was temporarily unavailable and asked me to wait an hour. After an hour, it was still unavailable, so to avoid delaying my trip, I took a Corolla with very poor performance. Currently, I am applying for a refund of the price difference, and I don't know the outcome yet.

I reserved a Mercedes C, and although I didn't get it, I would have been okay with a similar model. Instead, they downgraded me to an SUV, which is very unreliable. I booked this more than half a month in advance, and it still happened. Eventually, I found an Avis offline by myself, and they offered me a 5 Series at the same price. The online service is truly unreliable.

They didn't have the reserved car? What's going on?

They obviously had the Mercedes we wanted to rent but gave us a Peugeot instead, claiming it was the same type of car.

Not bad, very good, no extra unnecessary charges
