The rental car was from Sixt. Well, I don't necessarily skimp on that. It had to be a BMW 5 Series or similar, and the rate for 16 days was around €1,725. There was an additional €40 for returning it to the terminal.

Well, I was curious to see what they had. There was a long line at the counter, but when I told the employee I was a Platinum member, they immediately let me skip ahead of everyone else. Sure, that's great for the others. They told me I would get a brand new Audi A6 and that I was the first renter. They then tried to sell me the tank, explaining to the people next to me that the €2 they were paying was cheaper than on the street. Well, a liter costs around €1.70, and when you consider that there are always a few liters left in the tank at the end, it's obviously a great deal. We'd rather fill up ourselves at the end, despite the special price.
The A6 only had 10 kilometers on the clock, but it was from the old series (someone has to take the old cars) and had pretty basic equipment. The car had almost nothing, and the imitation leather made you sweat. The diesel engine, probably the smallest one, performed reasonably well. It was fine for Ireland.

That happens all the time if you don´t have a soft close (funny fact: BMW deletred it completely in the new 5 - thanks, you can keep it)

I think it could have been a little more for the price, but it was OK. Unfortunately, a hotel had pushed a rock halfway onto the parking lot (more on that later), which didn't look very nice.
A few things didn't work (traffic sign recognition, air pressure, etc.), but that's nothing new for cars from the Volkswagen Group (you know what I mean, I love mine at home and can't wait for my new one).

OK, the tire pressure was really too low (thanks, Sixt), but the other warning lights shouldn't have been on temporarily either.
I haven't received the bill for the damage yet, but I do have my final invoice. Who can find the fault?
I complained about this once, but haven't received a response yet. It's definitely rude.
Incidentally, the Toll Pass means that you don't have to pay online on some routes. If there are payment stations, you don't get a ticket, so you have to pay cash. That's how I imagined it would work.
P.S. Can anyone tell me what this very valueable sticker (worth a few Euro I guess) is? Some kind of code to scan?
