@chromosome16 They generally inspect rental returns in more detail in places outside the Americas
But don't need to buy high priced insurance from rental agencies, just read your cc coverage, it's not even hard to understand
I rented a MB c class estate from sixt in Portugal, didn't catch scratch on side of door, they billed 450 euros, my amex took care of it all, they let me choose if I want then to handle with rental agency or just reimburse me once the agency charges the card. I got credit within a few days after agency charged the card a month later
