The rental company aggressively promoted insurance, and their service attitude was very poor if you didn't purchase it. I calculated the insurance cost from the rental company, and it turned out to be similar to what was offered by the third-party platform. It’s better to buy directly from the rental company in the future because you don’t even have to pay a deposit after purchasing it. I initially rented a Toyota hybrid to save on fuel costs, but they gave me an old Spanish-made car instead, claiming it was the same class.
