ChatGPT

The best rental car company for most people is Enterprise, but it depends on whether you care most about price, airport convenience, vehicle selection, or avoiding hassles.

Here's how I'd narrow it down:

My top rental car companies

1. Enterprise Rent-A-Car — Best overall

A strong choice for customer service, neighborhood locations, and replacement vehicles if something goes wrong. Often my first choice for a regular vacation or business trip.


2. Costco Travel — Best for value

Worth checking if you're a Costco member. Compare its all-in rates and cancellation terms against booking directly with rental companies.


3. National Car Rental — Best for frequent travelers

Particularly appealing for business trips and eligible Emerald Club members who value a quicker pickup experience.


4. Budget — Best budget option to compare

Can offer competitive rates, especially when booked ahead. Check the final price, location reviews, and fees before booking.

For the latest national rankings, Enterprise took first place in J.D. Power's 2026 customer satisfaction study, with National second. Business Travel News That makes Enterprise my safest starting recommendation, though the specific rental location matters.

My advice: Compare Enterprise, National, and Alamo for the exact same dates and vehicle class. Look at the total price including taxes, mileage, insurance, and additional-driver fees.

One question so I can give you a better recommendation: Where are you renting the car, and what is it for?

Where will you pick it up?

At an airport

A local rental office


What is the rental for?

Vacation or road trip

Business trip

While my car is being repaired

Several weeks or longer


What matters most?

Lowest total price

Best overall experience and reliability

Fast, convenient pickup

Gemini

The "best" rental car company depends heavily on what you value most—whether that’s customer service, price, speed, or luxury.

The top rental car companies stand out in different categories:

1. Best Overall & Best for Customer Service: Enterprise

  • Why it’s great: Enterprise consistently ranks at the top of customer satisfaction studies (including J.D. Power surveys). RentRight They have a massive network of neighborhood and airport locations, meaning you can often find one nearby, and they even offer a "we'll pick you up" service at local branches. RentRight
  • Best for: Everyday rentals, first-time renters, and anyone who wants a smooth, stress-free counter experience. RentRight

2. Best for Frequent & Business Travelers: National

  • Why it’s great: National is famous for its Emerald Aisle loyalty program. If you hold status or join the club, you can bypass the rental counter entirely, walk straight out to the lot, and choose any car in your booked class (or upgrade for free). RentRight It saves massive amounts of time.
  • Best for: Business trips and frequent flyers who value speed and efficiency. RentRight

3. Best for Luxury & Modern Fleets: SIXT

  • Why it’s great: Originating in Europe, SIXT has heavily expanded in the U.S. and frequently wins top awards for its modern, high-end fleet. SIXT If you want to drive a BMW, Mercedes, or Audi without paying astronomical specialty prices, SIXT is usually your best bet.
  • Best for: Travelers looking for a premium vehicle, sleek app-based check-ins, and a touch of luxury. The Broke Backpacker

4. Best Budget-Conscious Picks: Budget, Alamo, or Thrifty

  • Why they’re great: If you are strictly looking at the bottom line, Budget (and sister brands like Dollar and Thrifty) frequently offer the lowest base rates. Alamo is also great for families and budget road-trippers, offering fast online check-in kiosks at major airports.
  • Best for: Cost-sensitive travelers and long road trips where the car is just a utility. Engine

Quick Tips for Getting the Best Deal:

  • Check Aggregators First: Sites like Discover Cars or Kayaks let you compare prices across multiple brands instantly.
  • Look at Bundles: If you are booking a flight or hotel, check platforms like Costco Travel—they often bundle steep rental discounts with perks like a free additional driver.
  • Watch out for Hidden Fees: Airport taxes, underage driver fees, and counter upsells for insurance can quickly inflate a "cheap" base rate. Always check what your personal auto insurance or credit card covers before declining or accepting rental coverage.

What type of trip are you planning (e.g., a family vacation, a business trip, or a weekend getaway)? I can help narrow down which company and loyalty program would suit you best.

Perplexity

For a traditional rental company in North America, Enterprise is a strong overall pick: it ranked first in the 2025 customer-satisfaction survey, with National second. The best choice still depends on location and price, so compare the total cost for your dates before booking.forbes.com

Grok

There is no single “best” rental car company—it depends on your priorities (price, customer service, convenience, vehicle selection, loyalty perks, location)—but recent data consistently ranks Enterprise Rent-A-Car and its sister brand National Car Rental at or near the top for overall customer satisfaction. morningoverview.com

Recent Rankings (2025–2026)

  • J.D. Power 2026 North America Rental Car Satisfaction Study (airport rentals, ~7,800 respondents):

    1. Enterprise (739/1000)
    2. National (726)
    3. Advantage (717)
    4. Alamo (716)
    5. Sixt (714)
    6. Hertz (711)
      Industry average: 707.
      Enterprise has led or finished near the top in most years since the early 2000s. Key drivers include ease of rental, pickup/drop-off, staff, vehicle condition, and trust. Getting the reserved vehicle class (or choosing a specific car) strongly boosts scores. www.jdpower.com
  • Travel + Leisure World’s Best Awards (reader votes, 2026): National #1, Enterprise #2, Sixt #3, Hertz #4, Alamo #5. National is frequently praised for its Emerald Club (skip the counter, pick any car in the Emerald Aisle with no upgrade fee for eligible members). www.travelandleisure.com

  • Business Travel News surveys: National has often ranked #1 for years among corporate travelers for clean cars, booking ease, and service. Enterprise is a close second. www.travelandleisure.com

  • Other notes: Enterprise Holdings (Enterprise, National, Alamo) generally outperforms Avis Budget Group and Hertz Global Holdings brands in satisfaction. Budget/Dollar/Thrifty tend to win on lowest base rates but score lower on service. Sixt often ranks well for newer/premium European vehicles and a more modern experience.

Quick Decision Guide

Priority Strong Options Why
Overall reliability & service Enterprise, National Highest satisfaction scores; large networks
Frequent/business travelers & skip-the-counter National (Emerald Club) Easy pickup, car choice on the aisle, loyalty benefits
Lowest price Budget, Dollar, Thrifty, sometimes Alamo Competitive base rates (watch for fees/upsells)
Premium/newer cars Sixt, National Strong vehicle quality feedback
Small towns / non-airport Enterprise Largest footprint by far
Loyalty / free days National or Enterprise Emerald Club, Hertz Gold Plus, Avis Preferred Status unlocks upgrades and free days

Practical Tips

  • Compare prices for your exact dates and location—rates fluctuate a lot. Use the companies’ sites plus aggregators, and check Costco Travel, AAA, or credit-card portals for member discounts.
  • Join the free loyalty program of your preferred brand before booking (Emerald Club for Enterprise/National/Alamo is especially useful).
  • Inspect the car thoroughly (photos/video of any existing damage) and understand insurance (credit cards often cover CDW; decline the rental company’s if you’re covered).
  • Book early for popular locations/dates, and note that airport locations can have higher fees and longer lines than neighborhood branches (Enterprise shines off-airport).
  • Alternatives like Turo (peer-to-peer) can be cheaper or more flexible for certain trips but come with different risk/reliability profiles.

Bottom line: For most people prioritizing a smooth, reliable experience, start with Enterprise (especially off-airport or if you value broad availability) or National (especially at airports if you can use Emerald Club). Always shop the specific itinerary, as the “best” for you is the one that balances price, convenience, and service for that trip.
