A word of caution about renting a car on Cozumel. The price quoted to you or mentioned on this board likely is for a standard transmission. Automatic transmission is about 30% + or more, if the rental company even has it. We are just back from a trip and I learned that the hard way and wasted a lot of energy one day trying to rent a car I couldn't drive. So check the transmission type before you rent if that also is an issue for you.
