2. How to choose the right car rental comparator in the USA?

To rent a car in the United States, the best choice remains a comparator that is also a distributor like Authentik USA. Unlike simple search engines, this type of platform not only allows you to compare offers, but also to book directly, with clear conditions, readable insurance, and an identified contact in case of problems. This is an essential criterion to avoid unpleasant surprises once on site.

Why choose a comparator that is also a distributor?

Not all car rental sites work the same way, and this difference has a direct impact on the final price, insurance, and customer service. A comparator, distributor (OTA) or a broker sells the rental directly, which means they can provide more complete conditions and are responsible for the booking, unlike comparators that only redirect to third-party sites.

“In the United States, comparing prices is not enough. What makes the difference is booking with a provider who understands insurance, local conditions, and the constraints of a road trip. That’s exactly why Authentik USA exists.” Simon, co-founder of Authentik, Linkedin

Are direct rental companies (Alamo, Avis, Sixt…) and peer-to-peer platforms (Turo) a good solution?

Direct rental companies and peer-to-peer platforms can seem attractive, notably because of their reputation or displayed prices. However, they don’t allow you to compare several offers with each other and often require you to handle insurance, deductibles, and rental conditions more independently. With peer-to-peer platforms, levels of coverage and rules can vary greatly from one vehicle to another, making things complicated for an uninitiated traveler.

3. What are the best tips for renting a car in the USA?

Booking a car in the United States is not just about choosing the lowest price. With the distances to cover, insurance options, mandatory extras, and each State’s specific rules, a few good practices can help you steer clear of unpleasant surprises.

Book in advance and match the vehicle to your itinerary

In the United States, the earlier you book, the better your chances of getting a good rate and, above all, the type of vehicle truly suited to your trip. SUVs, minivans, and automatic cars are in high demand, especially for road trips and family vacations.

It’s also important to match the vehicle to your itinerary: long distances in the American West, mountain roads, national parks, or city driving on the East Coast. A vehicle that is too small, or not suited to your needs, can quickly affect the comfort of your trip.

Fully understand insurance, additional fees, and rental conditions

Insurance remains one of the most sensitive points in car rental in the United States, but it always goes hand-in-hand with rental conditions.

💡 It’s vital to check exactly what’s included: deductible, liability insurance, coverage for theft or damages, as well as any possible exclusions.

There are also certain contractual conditions, such as geographical restrictions, minimum driver age, or rules unique to each rental company.

Also be wary of additional fees:

• additional driver
  
• young driver
  
• fuel policy
  
• drop-off fees in another city if you have a one-way rental
  

These elements can significantly affect the final price between booking online and picking up the car.
