The minimum age to rent a car is 21 years old However, drivers under 25 may face additional fees, restrictions on vehicle types, and may need to provide a higher deposit

Generally, you cannot book a rental car entirely for someone else, but you can book it in your name and add them as an authorized driver. The person picking up the car must be present, provide their own valid driver's license, and a credit card in their name

Consider booking directly with the rental company's website after your initial search, as they may offer "Pay Now" options with steeper discounts. 

When selecting a rental car, consider your needs, such as space and fuel efficiency, compare prices and insurance options, and thoroughly inspect the vehicle before driving off.
