Before renting, check if your personal auto insurance extends to rental cars. Many policies and credit cards offer rental coverage, helping you save on insurance costs.

Some companies may provide a complimentary tank of fuel with your rental. Understand the conditions, such as how much fuel you need to return with to avoid fees.

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.

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.

Most rental companies will require a credit card for the deposit, which is typically frozen in your account. Make sure to inquire about the specific deposit amount and the policy for releasing the freeze.

When selecting insurance, consider if it includes free excess coverage. This means you won’t have to pay a deductible in the event of damage, adding an extra layer of security.

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.

Familiarize yourself with the fuel policy for your rental. A 'Full-to-Full' policy means returning the car with a full tank, while 'Same-to-Same' indicates you return it at the same fuel level. Full-to-Full is usually more economical.
