Most car rental companies will ask for a credit card deposit, which is usually held temporarily. Inquire about the specific deposit amount and the process for releasing it once the rental is complete.

To evade additional charges, return the rental car on schedule. Familiarize yourself with the agreed return time to prevent any surprises.

Prior to booking, check for any current promotional offers or discounts. Many rental agencies provide seasonal deals or early booking discounts.

If you're looking for more comfort or features, inquire about upgrade options at the rental desk. Sometimes, upgrades are offered at a discounted rate at pickup.

Many rental companies require payment by credit card and may not accept debit cards. If you only have a debit card, check the rental company's payment policies in advance and look for suitable options.

Before booking, review the rental agreement for any hidden fees such as airport surcharges, additional driver fees, or late return penalties. Understanding these can help you budget more effectively.

Some rental companies offer a free tank of fuel with your rental. Be sure to understand the terms, including how much fuel you need to return the car with and any potential fees for not meeting these conditions.

If you have a specific vehicle model in mind, consider rentals that guarantee the car type you want. This avoids surprises at pickup when you receive an alternative vehicle.
