What do you need to rent a car in O'Fallon?

Where can I find an O'Fallon car rental if I am younger than 25?
Age policies differ between rental companies, so you'll have to do a little shopping around. Managed to find an O'Fallon supplier that does rent to drivers under 25 years of age? That's great!
