Where to look for rental cars

Rental cars are available through three main channels: national chains, local independent companies, and online booking sites that search multiple providers at once. National chains like Enterprise, Hertz, Budget, and Avis have locations at most airports and city centers, which makes them straightforward to find but often more expensive. Local rental companies operate in specific regions and sometimes offer lower rates, though their fleets and hours may be more limited.

Online booking aggregators—including Kayak, Autoslash, Priceline, and Hotwire—let you compare prices across many rental companies in one search. These sites show you the total cost upfront, including taxes and fees, which national company websites sometimes hide until checkout. You can also book directly through a rental company's website if you already know which one you want.

Airport rental counters are convenient but typically charge facility fees on top of the daily rate. Off-airport locations in the same city are usually cheaper. If you're renting for more than a week, some companies offer weekly rates that work out to less per day than daily pricing.

Key Takeaways

  • National chains, local companies, and online booking sites each have different price points and availability, so comparing across all three types usually saves money.
  • The total cost shown on booking sites includes taxes and fees, while rental company websites often add these at checkout, making direct comparison difficult.
  • Airport locations are convenient but charge extra facility fees; renting from an off-airport branch in the same city typically costs less.
  • Weekly rates are often cheaper per day than daily rates, so if you need a car for five or more days, ask about weekly pricing.
  • Your personal auto insurance, credit card, or employer may already cover rental cars, so check before buying the rental company's damage waiver.

What information you'll need to provide

When you search for a rental car, you'll need your driver's license number, the dates and times you want to rent, and your pickup and dropoff locations. If those locations are different, you'll pay a one-way fee. Most rental companies require you to be at least 21 years old; drivers under 25 may face an additional daily surcharge called a young driver fee.

At pickup, you'll show your driver's license, provide a credit card for the deposit and any charges, and sign the rental agreement. Some companies ask for a second form of ID. If someone else will be driving the car, they must be listed on the agreement and present their own license—you cannot straightforward add a driver later. Read the agreement carefully before signing, especially the section on damage coverage and mileage limits.

Understanding rental costs and fees

The daily rate is only part of what you'll pay. Taxes vary by location but typically add 10 to 20 percent to your bill. Facility fees at airports can add $5 to $15 per day. If you decline the rental company's damage waiver and damage the car, you're responsible for repairs, which can cost hundreds or thousands of dollars.

Mileage limits differ by rental type and company. Some unlimited-mileage plans charge the same rate whether you drive 50 miles or 500 miles. Others charge per mile once you exceed a daily limit, which adds up quickly on long trips. Fuel charges depend on whether you return the car with a full tank or pay the company's per-gallon rate, which is usually higher than gas station prices.

Late return fees kick in if you bring the car back after your agreed time, even by 30 minutes on some contracts. Young driver fees, GPS rental charges, and additional driver fees are common add-ons. Always read the "Fees" section of the quote before booking.

Checking insurance and damage coverage

Before you buy the rental company's damage waiver, check whether your own auto insurance covers rental cars. Many personal policies do, though some exclude certain vehicle types or rental locations. Credit card companies often provide rental car coverage if you charge the entire rental to that card—but the coverage usually applies only if your personal insurance doesn't cover it first.

If you're renting through your employer or a business account, your company's insurance may cover the car. Call your insurance agent or credit card company before you rent to confirm what's covered and what isn't. Get the answer in writing if possible, because you'll need proof if you have to file a claim.

The rental company's damage waiver (also called a collision damage waiver or CDW) typically costs $15 to $30 per day and covers damage to the rental car. It usually doesn't cover theft, glass damage, or damage to the undercarriage. If you decline the waiver and have an accident, you're liable for the full repair cost, even if the accident wasn't your fault.

Booking strategies to lower your price

Prices change constantly, so booking 1 to 3 weeks in advance often gives you better rates than booking the day before. However, if prices drop after you book, some sites and rental companies let you rebook at the lower rate. Check the cancellation policy before you book—free cancellation up to 24 or 48 hours before pickup gives you flexibility to rebook if prices fall.

Membership programs through AAA, AARP, or your employer sometimes include rental car discounts. Loyalty programs with individual rental companies offer discounts on future rentals. Booking through a corporate account or travel agency can also lower the rate, even if you're renting for personal use.

Comparing the same car type across multiple sites usually reveals price differences of $10 to $50 per day. Autoslash and Kayak let you set up price alerts, so you'll know if the rate drops after you book. Off-peak times—weekday rentals and rentals outside summer and holiday seasons—are almost always cheaper than peak times.

What to check before you drive away

Before you leave the rental lot, walk around the car with the rental agent and point out any existing damage—dents, scratches, stains, or broken parts. The agent should note these on the agreement. Take photos or video of the car's condition from multiple angles, including the interior, tires, and undercarriage. This protects you if the company tries to charge you for damage that was already there.

Check that the fuel gauge matches what the agreement says (usually "full"), test the lights and wipers, and make sure you know how to operate the car's features. Confirm the mileage on the odometer. If anything is broken or unsafe, tell the agent when ready and ask for a different car.

Keep your rental agreement and all receipts. If you buy gas, keep the receipt. If you pay for parking or tolls, keep those receipts too. When you return the car, the agent will inspect it and compare its condition to the photos and notes from pickup. Having documentation protects you if there's a dispute about damage or charges.

Returning the car and handling disputes

Return the car on time and with a full tank of fuel, unless your agreement specifies otherwise. Some rental companies charge a fuel surcharge if you return the car empty, even if you pre-paid for a full tank. Take a photo of the fuel gauge and odometer at return, and get a receipt showing the car's condition and mileage.

If the rental company charges you for damage you didn't cause, contact them in writing within 30 days and include photos from pickup, your rental agreement, and any other evidence. If they don't respond or refuse to adjust the charge, file a dispute with your credit card company. Your credit card issuer can often reverse the charge if you provide documentation that the damage was pre-existing.

Keep all documentation—agreement, receipts, photos, and correspondence—for at least 60 days after you return the car. Some charges appear on your credit card statement weeks after return, so monitor your account for unexpected fees.

Frequently Asked Questions

Can I rent a car if I don't have a credit card?

Most rental companies require a credit card for the security deposit, even if you pay with cash or debit. Some locations accept a debit card with a larger hold, but policies vary. Call the rental company before you book to ask whether they accept debit cards and what deposit amount they'll hold.

What happens if I return the car late?

Late return fees typically start 30 minutes to 1 hour after your agreed return time and can range from $25 to $75 or more per day. Some companies charge a full day's rate if you're even slightly late. Check your agreement for the exact grace period and fee amount, and plan to return the car well before your important date.

Can I add a driver after I pick up the car?

No. All drivers must be listed on the rental agreement at pickup and present their license at that time. Adding a driver later is not possible. If someone else needs to drive, you'll have to return to the rental location, add them to the agreement, and pay any additional driver fee.

Is it cheaper to rent from an airport or a city location?

City locations are usually cheaper because they don't charge airport facility fees. However, you'll need transportation to the city location, which may cost more than the savings. Compare the total cost—rental rate plus transportation—before deciding.

What should I do if the rental car breaks down?

Call the rental company's roadside information number when ready. The number is on your rental agreement and usually on a card in the car. The company will arrange a tow or send a replacement vehicle. You're not responsible for the breakdown unless you caused it through misuse or failure to maintain the car as required by your agreement.
