Look up fuel prices in the area where you'll return the vehicle. Refueling at a local station is often more economical than paying rental company rates.

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.

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.

Always keep your rental agreement, identification, and insurance information easily accessible during your rental period. This can help resolve any issues quickly.

Before leaving the rental lot, inspect the vehicle for any pre-existing damage and ensure it’s recorded. Taking photos can help avoid disputes upon return.

Select a pickup spot that is easy for you to reach. Many rental companies offer locations within airports for quick access, while others may require a shuttle.

If you plan to share driving, check if the rental company allows a second driver and whether there are additional fees. Some companies offer free second driver options under certain conditions.

Before departing, check the interior of the rental car for cleanliness and any functional issues. Ensure equipment like the radio and air conditioning works properly.
