Picked up the car at midnight, service was good. However, the oil light came on and they were out of spare oil, so we had to go to a gas station to add oil. Fortunately, we insisted that they come with us, and it took visits to two gas stations to find oil. Speaking English didn't work well in the German-speaking region. Schengen area at midnight, not easy.

The airport location is well-marked. When handling the paperwork, you'll receive a parking card with the parking spot number. Follow the number to find the car in the lot. To exit, just insert the card into the ticket machine.

The car rental process was straightforward and convenient, with quick pickup, fast inspection, and clear charges. They upgraded us to an Alhambra, which had great power.

Convenient

Like: Clean car, matched the size we had ordered although not the brand. Easy to collect (after the long queue) and drop off at Munich railway station although you need to keep your eyes peeled to find the drop off garage.
Dislike: We queued for nearly an hour at Munich airport to pick up the vehicle even with the ticket system. The ticket machine needs to be more obvious or at least a more obvious sign.
