Top 5 car rental companies with the best car fleets in the USA

With approximately 4.18 million miles of highways, the US is a top-notch destination to cruise on wheels. That is why, more than 70 million people use a rental car to travel around the country. 

Indeed, having a vehicle at hand gives you multiple perks compared to a bus, train, and even a plane. Freedom of movement, complete independence from schedules, comfort in any weather, and a cheap price to mention a few. However, the difficulty of choosing the right provider can overshadow the enjoyment of the road trip ahead. After all, you have many criteria when deciding on a company. 

One of the dominant characteristics and indicators of any agency is its vehicle fleet. What do we mean? Imagine that you are going on a family ride and are looking for a rental 8-seater minivan. You would probably like to know which rental car companies have 8-passenger minivans in this case. Fortunately, almost every supplier can offer you a well-maintained car rental for 8 people in the desired location. 

And yet, which companies have the widest choice, not only of people carriers but cars of other classes? We’ve done a lot of research and are ready to share the results with you – keep reading for the full details! 

General US fleet and groups available 

According to official data, last year the total lineup of companies was 1.8 million vehicles. However, this is lower than in the pre-COVID season, which means that agencies haven’t yet had time to replenish the required amount. Most autos belong to the economy through full-size categories, while specialty groups such as luxury, convertibles, minivans, and passenger vans are less popular. Therefore, providers have fewer of these on the list. Let’s review all the vehicle categories on offer from providers in the US. 

  • Mini – perfect for solo travelers or couples 
  • Economy – seats up to 4 people and has outstanding fuel economy 
  • Compact – slightly larger than the Economy models and offers a larger trunk 
  • Mid-size – a great combination of cheap price, high fuel economy, and roomy interior 
  • Standard – fits comfortably up to 5 people and has ample legroom 
  • Full-size – the best choice for a small family of 4-5 with lots of luggage 
  • SUV – feels confident on any road surface and features excellent 4×4 ability 
  • Minivan – the perfect solution for a small group trip with family or friends 
  • Passenger van – satisfies the travel needs of a large group, and has plenty of head and legroom 
  • Cargo van – holds bulky items and solves most transport issues 
  • Premium – provides more comfort than you get in a regular sedan 
  • Luxury – perfect for business meetings, dates, and other special occasions in your life 
  • Exotic – a car with a stylish design, a powerful engine, and a top-class interior 
  • Convertible – allows you to drive with the wind blowing through your hair
