You've seen the posters. A vintage Mustang sitting outside a neon-lit diner in the middle of the Mojave. It looks perfect. But honestly, if you're actually planning a Route 66 car rental, the reality is a lot messier than a postcard. It's 2,448 miles of highway stretching from Chicago to Santa Monica, and choosing the wrong set of wheels is the fastest way to turn a bucket-list dream into a logistical nightmare.
The Mother Road isn't one single road anymore. It's a patchwork. You're hopping between modern I-40 bypasses, crumbling two-lane blacktop, and gravel frontage roads that haven't been paved since the Eisenhower administration.
Most travelers make the mistake of thinking any mid-sized sedan will do. They're wrong. You aren't just renting a car; you're renting a mobile home for two weeks.
The One-Way Fee Reality Check
Let's talk about the elephant in the room: the one-way drop-off fee. Because almost nobody drives Route 66 in a loop, you’re likely picking up a car at O'Hare and dropping it off at LAX. Rental companies like Hertz, Enterprise, and Avis aren't exactly doing you a favor here. They have to get that car back to Chicago somehow.
Expect to pay anywhere from $500 to $1,000 just for the privilege of leaving the car in California.
Some people try to "hack" this by booking through European aggregators or specialized sites like DriveUSA.de, which often bake the one-way fee into the total price for international travelers. It's a weird quirk of the industry, but it works. If you're a domestic traveler, you're basically stuck hunting for "drive-back" specials or just swallowing the cost as part of the adventure.
It’s expensive. It’s annoying. But it’s the price of entry.

Why the "Classic Car" Dream is Usually a Bad Idea
Everyone wants the 1965 Corvette. I get it. But unless you are a literal mechanic or have a massive budget for a specialized specialty rental from a place like Blacktop Corvettes or a private Turo host, you should probably reconsider.
Old cars break. They don't have modern AC.
Try driving through the Texas Panhandle in July without a modern cooling system. You'll be miserable. Most standard Route 66 car rental options are going to be your typical fleet: Malibus, Altimas, or the occasional Mustang convertible. If you want that "classic" feel without the breakdown risk, the Ford Mustang or Chevrolet Camaro convertibles are the go-to choices for a reason.
Just keep in mind that trunk space in a convertible is a joke.
If you have two suitcases, they aren't fitting in the back of a Mustang with the top down. You’ll end up with luggage in the backseat, which makes you a prime target for opportunistic theft when you’re parked at a roadside attraction in Amarillo or Albuquerque. Honestly, a mid-sized SUV is the "boring" but smart choice for 90% of people.
The Terrain You'll Actually Face
- Illinois and Missouri: Mostly flat, easy cruising, but plenty of stop-and-go through small towns.
- Oklahoma: Long stretches of original 1920s "ribbon road" that are barely nine feet wide. You'll want a car with good tires.
- New Mexico and Arizona: High altitudes. If you rent a base-model economy car with a tiny engine, it will struggle to climb the grades near Flagstaff.
- California: Traffic. Brutal, soul-crushing traffic once you hit San Bernardino. You’ll want an automatic transmission.
Insurance: Don't Be Cheap Here
Usually, I tell people to skip the rental counter insurance because their credit card covers it. For Route 66, I change my tune. This is a long trip. You are crossing eight states. The chances of a cracked windshield from a pebble in Oklahoma or a fender bender in a rainy St. Louis are statistically much higher than on a weekend trip to Vegas.

Loss Damage Waiver (LDW) is your friend.
If you get a chip in the glass—and you probably will—you want to be able to hand the keys over at LAX and just walk away. No paperwork. No insurance adjusters calling you three weeks later.
Rental Secrets the Big Brands Don't Mention
Check the mileage policy. Most major US rentals are "unlimited mileage," but double-check the fine print. You're putting 2,500+ miles on this thing. If you accidentally book a "local" rate with a 200-mile-a-day cap, you’re going to get hit with a massive bill at the end.
Also, consider the sun.
The "westbound" drive means the sun is in your eyes every single afternoon. If you’re renting a car with a massive dashboard, ensure it’s a dark material. Light-colored tan dashboards reflect off the windshield and make visibility a nightmare in the Mojave desert heat.
Managing the Logistics
Don't wait until you arrive at the airport. Route 66 car rental demand spikes in May and September (the best months to drive). If you try to book a convertible at the counter in Chicago in September, you'll either pay $200 a day or end up in a Dodge Caravan.

Book your car at least three to six months out.
And here is a pro tip: Join the loyalty program for whatever company you use (Gold Plus, Emerald Club, etc.). It’s free. It lets you skip the line. After a long flight into O'Hare, the last thing you want is to stand in a two-hour queue behind forty other people trying to live their Americana dream.
What to Check Before Leaving the Lot
- The Spare Tire: Many modern rentals just have a "fix-a-flat" kit. On the remote stretches of New Mexico, that won't help you if a sidewall tears. Demand a car with a real spare.
- Tire Tread: You're driving across half a continent. If the tires look bald, swap the car.
- USB Ports: You'll be using GPS for 14 days straight. Ensure the charging ports actually work.
Finalizing the Plan
The Mother Road is about freedom, but that freedom is built on a foundation of boring stuff like rental agreements and insurance tiers. If you’re flying in from overseas, look specifically for "all-inclusive" packages that cover the CDW and the one-way fee upfront. It avoids the "hidden cost" shock at the end of the trip.
Get the SUV if you want comfort. Get the Mustang if you want the photos. Just don't get the economy sub-compact. You'll regret it by the time you hit the Ozarks.
Actionable Next Steps:
- Compare one-way fees: Search your dates on a site like Kayak, then compare it against a specialized broker like Auto Europe to see if the one-way fee is hidden or transparent.
- Map your luggage: If you're dead-set on a convertible, pack soft-sided duffel bags instead of hard shells. They squash into weird trunk shapes much better.
- Join a loyalty program: Sign up for National Emerald Club or Hertz Gold today so you can bypass the Chicago counter.
- Verify your insurance: Call your credit card company and ask specifically if they cover "long-term rentals" (some cap at 15 days) and "one-way rentals."
