Cheap National Car Rentals at Detroit Willow Run Airport, YIP

When renting a car, understand the fuel policy. A 'Full-to-Full' policy means you return the car with a full tank, while 'Same-to-Same' means you return it with the same level of fuel. Full-to-Full is often more cost-effective.

If you have a specific vehicle in mind, opt for rentals that guarantee your chosen car type. This ensures that you receive the vehicle you expect, rather than being offered an alternative.

When renting a car, it's crucial to understand the different insurance options available. Selecting the right insurance can protect your finances in case of an accident. Common options include Collision Damage Waiver (CDW) and liability insurance, so make sure to confirm the required coverage with the provider.

Research fuel prices in the area where you'll return the vehicle. Filling up at a local station may be cheaper than paying for fuel through the rental company, especially if they charge higher 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.

Check the operating hours of your rental company, as some may have limited hours at airports.

If sharing driving responsibilities, check the policies regarding additional drivers. Some companies charge fees for each extra driver, while others may include it for free under certain conditions.

Allow for possible delays at the rental desk, particularly during busy travel times.
