Trying to book a car for hire, but all the companies offer different things like levels of insurance, what is covered and what isn't, damage waivers, total damage waivers etc.
If you have rented a car before, what is the most important thing to look for. Basically if I smash it to pieces, I don't want to have to pay to repair it . Also only being 22, not all companies will let me have a car, so I am a bit limited for choice. But any help will be appreciated. Canary Islands is location, so its in Europe.
