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?

Easy pickup. Minimal upselling.

The entire process was quite smooth, and both pick-up and return were handled professionally.

The car rental company was excellent, providing attentive service. They upgraded our vehicle because we didn't have enough space for our luggage.
