Island Tour, Santorini is small but beautiful

I have nearly ten experiences of renting a car abroad, and this is the worst condition I've encountered. The car is very old (possibly 10 years old) and has been repainted, without an office address for the rental company. The car's condition is extremely poor (the brakes make strange noises, and there's a fear it won't stop on steep slopes). The car is old with dented doors and numerous scratches. Since there was no documentation to indicate car damage (very irresponsible), we had to meticulously take photos as evidence. There was so much damage that we took around 150 photos, spending over an hour under the hot sun, which was very inconvenient on the roadside, hampering other cars and requiring us to move the car. The lighter socket was also broken, so we couldn't charge our phones, which was very inconvenient. If you are not returning the car near the airport, such as at a port, you need to pay an additional 15 euros in cash (even though the staff is driving to the same place, not sure why there’s a difference?!) If you need to pick up or return the car an hour or two earlier, there are extra charges, and there's no flexibility with only specific times every two to three hours for pick-up and return. This is the first time I’ve encountered such a rental company, it took us half a day. I recommend avoiding this company in Santorini.
