Overall, it was quite good. The drop-off process was efficient, with no damage or accidents. They upgraded me from a Peugeot 208 to a Citroën C3 manual diesel. The car had over 80,000 kilometers on it. I had to add AdBlue myself, costing over 16 euros. QEEQ mentioned I could get reimbursed from the rental company, but I threw away the receipt. Sisilybycar doesn't charge extra for cross-country trips, which is great!

This is one of the bigger companies around, the pickup and drop-off were quite fast. They charged a 650-euro pre-authorization, which I think hasn't been released yet. Overall, a good experience. Italy is very suitable for self-driving, except for the high parking costs. For experienced drivers, the basic insurance is usually enough, no need for full coverage, as locals drive and park very orderly. A word of caution, this parking lot can be tricky. After picking up the car, the rental company's parking area will issue a parking card. When you leave the parking building, you should insert the card into the machine for automatic gate open. However, it didn't work for me, so I had to call for manual assistance to open the gate. As a result, it continued to count as if the car was still inside, and I only noticed in the evening in Naples, ending up paying a 33-euro parking fee. In such cases, after exiting, immediately park on the side and use the 'easy parking' app provided on the receipt to scan and pay quickly.

Excellent!

After we returned the car it took nearly 1 month to get back our deposit - service was very slow.

The staff behind the counter had told us that she will charge us an additional 100 euros for a second driver. Even though we did not agree as we did not think it mattered how many people drove the car, in any case due to no choice we agreed and took the car. They had taken a deposit of euro 594 from my credit card and mentioned that they will return euro 400 when the car was returned in good condition. However when we returned the car and got a no damage on the car while being returned, they have still only returned euro 229.04 to my credit card instead of euro 400. This is unlawful. They are not picking up the toll free numbers that are listed and we have no way to talk to them. I am very disappointed.
