Hertz is a leader in the global car rental industry. There are 1,900 car rental stores in the United States throughout the country, and there are 6,600 car rental stores around the world. There are numerous models and short-term rental services - daily, weekly and monthly rentals.
Advantages: Gold card users go directly to HERTZ's parking lot and will see a sign with their own name and corresponding parking position. No contact is needed (the same type of reserved vehicle is often booked and automatically upgraded. To a better car, sometimes a luxury car such as Lincoln, you can swipe your card when you return (if the registered account already has a credit card, save it).
Disadvantages: expensive.
Avis
Avis is an internationally renowned multinational car rental company with more than 60 years of history. If Hertz is the largest in the world, Avis is the second largest in the world.
Advantages: First, the service is good—Most airports in the United States (and major cities with convenient transportation) have outlets, online booking is quick, even without having to fill in driver's license and credit card information; online changes and cancellations are also very convenient; Pick up the car, the efficiency is also good, almost never lined up, and the location of the parking lot and garage is also very convenient; Second, the car is very new, each time is given a new car that only opened thousands or even hundreds of miles.
Disadvantages: It's a little cheaper than Hertz.
Car rental episode: There are netizens sharing that he had a car accident while renting an Avis car (no one was injured, nor was it the responsibility of the netizen). After a high-speed rear-end collision, the rear car hit the netizen severely, so the netizen hit the front. At that time, the netizen opened a new Chevy Impala car that was only a few hundred miles in total. He thought that AVIS should feel bad and he immediately drove back to the airport. Unexpectedly, in Avis it took only a few minutes to fill in an accident report and immediately get a better car to drive away without any cost. The next day the netizen remembered that something had been forgotten in the car, and Avis also helped the garage to get it back, waiting for the netizen to take it off the next time he passed the airport. (This service is really good! Sure enough, a penny, a delivery...)
Enterprise
Advantages: cheaper than the above two. And Enterprise can talk about the price, it looks like each salesman has a performance assessment, so you can let them give you the biggest discounts, such as my friend's appointment to rent 10 days cut 100 knife ... ...
Disadvantages: Garage location and service are worse than AVIS and HERTZ. It may take 1-2 minutes to register at the pick-up counters of the above two companies. Enterprise is about 5 minutes, and it is not counting the time at the counter. The car seems to be old.
Another disadvantage is that the company has certain restrictions. For example, a car rented in this state cannot go outside the state. (Small series of research: from the airport's corporate car rental without this restriction, from other places Enterprise Car Rental, will see similar terms: Mileage Restrictions "MILEAGE IS UNLIMITED WHEN VEHICLE REMAINS IN ARIZONA, NEVADA, AND CALIFORNIA. VEHICLES ARE NOT ALLOWED OUTSIDE OF THESE STATES.")
Alamo
Alamo and Enterprise, similar to Enterprise, aim at the mid-range market, and usually have outlets at the airport. However, the location and staffing of the Alamo are much worse than the HERTZ and AVIS aimed at business users. There are often long queues at the front of the car counter.
Other Finally, there are many local small car rental companies that can come out of Google. Although they are cheap, the service efficiency and the oldness of the car should not have any expectations. 
4. Supplemental services such as GPS and baby seats. GPS charges according to the number of rental days, with Chinese voice prompts. If you have a navigator in your country, you can go online or on Taobao to find out if there is a North American map of your model and take it to the United States. The navigation software includes Garmin, TomTom, and iGO (the use of navigation software is otherwise introduced), and the results are good. It is recommended that drivers with baby travel use the baby seat service. 
5. Driver's License Notarization Most states in the United States have already accepted the new version of China's driver's license, which is a bilingual Chinese and English driver's license. However, this does not guarantee 100% of the situation. For example, we rented hertz and thrifty in San Francisco, and thrifty requested a driver's license and hertz did not. Similarly, when renting a car at thrifty in Las Vegas, the counter staff did not look at anything. Therefore, to be on the safe side, do a notarization in the country in case of emergency.
As we all know, the United States is the country on wheels. Not to mention that every household here is almost a handy car, and the car rental industry here is also very developed. Car rental procedures are simple and can be handled with orders, driver's licenses and credit cards. After completing the formalities, the key is inserted in the car. You can leave your car without leaving the airport. but! That being said, people who have experienced car rental for the first time in the United States are bound to be in a hectic state—too many things to deal with, where to sign the contract, and what time to look carefully at the terms! Therefore, Xiao Bian summed up the comparison of the following netizens with the major American car rental companies, and there are some related issues. 1. Comparison of major car rental companies in the United States with Hertz 2. Vehicle type literacy economy (economy, such as Sail), compact (compact, such as Jetta), Mid-Size (medium car: Rugao), full-size (large car: such as Regal), SUV, luxury ( Luxury type: such as Mercedes-Benz), Wagon (travel limousine, suitable for four people and more luggage), Van (van) 3. Vehicle insurance Most car rental companies quote only rents and taxes, not including insurance, because local people rent cars usually do not need to purchase additional insurance, but in the United States, we are "foreigners" and must purchase insurance separately. To protect one's own safety, you must purchase LDW Loss Damage Waiver or CDW (Collision Damage Waiver), SLI Supplemental Liability Insurance or (ALI Additional Liability Insurance). Personal Personal Accident and Effects (PAE) or Personal Effects Insurance (PEI), including drivers and passengers. When you have already purchased travel insurance, you can save on this small expenditure.
