Let me look at what you have searched and viewed. One moment please. Santiago is normal office hours, thats the first thing that would affect results.

Can you come earlier? If so try the link I just sent to you.

Even the airport doe snot have any large SUV, must be that particular week.

So 2 cars is all I can suggest.

The website is in real-time, so what you see is what is available and it will react to any search criteria, look here under " IMPORTANT INFORMATION " :-

The driver must have held a full driving licence for at least one year. At STEP2, click on the link "IMPORTANT INFORMATION' displayed to the right of the car photo of your choice. This will open another smaller window and if you click on "DRIVER" you will see what age restrictions there may be and any associated fees. Try a few different car models / suppliers, as they do differ.

For example HERTZ have an extra young drivers fee

Young driver's age: 21 to 24 years. Charge 27.85 EUR per day. Maximum 278.5 EUR. Includes 21% tax
