Car rental modalities

Hello, I would like to know what kind of modalities exist in the cars agencies in Renting and how are the payments

You get in Google and you rent cars, the first result that comes out www.rentalcars.com/ and Contination Elijes Pais, city and others and there is everything.

If what you are looking for is the type of the type to have a car daily and they take care of all the maintenance and when you want you change it. You can only that option if you are a company.
