10 tips to save on your car rental in and around Brentwood

1. Use filters to find the right car: Refine your search by vehicle type and features. Whether you require an SUV for added space, a convertible for summer drives, or an economical car for budget-friendliness, utilize filters on Expedia to help you discover the perfect match for your journey.
2. Book in advance to help lower costs: Rental prices can vary based on demand, so it’s advisable to reserve your vehicle well ahead of your trip. By booking in advance, you are likely to secure lower rates and enjoy better availability, particularly during peak seasons.
3. Consider a smaller car for savings: Smaller cars typically cost less to rent and are easier to park in crowded areas. Mid-size rentals strike a good balance between cost, comfort, and fuel efficiency.
4. Age guidelines: Drivers under 30 may encounter higher deposits or daily surcharges, and certain vehicle types—such as SUVs or premium models—might be unavailable. This can also apply to renters over 70 years old. Always verify the age requirements before finalizing your booking.
5. Check fuel policies: Some rentals operate under a full-to-full fuel policy, meaning you must return the vehicle with a full tank to avoid additional charges. This is generally the most favorable option. Others may provide full-to-empty or prepaid fueling options, which are acceptable as well—just ensure you return the car empty in that case.
6. Save on city and airport pickups: Picking up your rental car at airports often incurs a surcharge, but the added convenience may make it worthwhile.
7. Know your payment options: Many car rental companies only accept credit cards for payment.
8. Understand your insurance coverage: Car rental insurance can help you avoid unexpected expenses and provides peace of mind if something unforeseen occurs during your trip. It’s easy to add car rental insurance when booking through Expedia.
9. Consider unlimited mileage: If you’re planning long road trips, look for rental options that include unlimited mileage to steer clear of extra charges.
10. Bring your driver's license and ID: A valid driver's license is necessary to rent a car.
