It's the first thing almost every used car shopper in the Chicago area checks. Before the color, before the features, before the price — they look at the odometer. And while mileage does matter, it does not tell the full story. Not even close.

At Autos of Chicago in Arlington Heights, we sell vehicles ranging from a few hundred miles to over a hundred thousand. And after more than 9,000 cars sold since 2015, the one thing we can tell you with certainty is this: a well-maintained car with 80,000 miles will almost always outlast a neglected car with 30,000 miles.

Here is everything Chicago-area buyers need to know about mileage before making their next purchase.

What Is Considered Normal Mileage on a Used Car?

According to the Federal Highway Administration, the average American drives approximately 13,500 miles per year. That gives you a simple baseline to evaluate any used vehicle:

A 2-year-old car should have roughly 25,000 to 30,000 miles. A 3-year-old car should have around 36,000 to 42,000 miles. A 5-year-old car should have somewhere between 60,000 and 70,000 miles. A 7-year-old car would typically sit between 85,000 and 100,000 miles.

If the mileage is significantly lower than these benchmarks, that can actually be a sign of concern — a car that sits unused can develop issues with seals, fluids, and rubber components. If the mileage is significantly higher, that tells you the car has been driven hard and you need to look more carefully at the service history.

What We Have in Stock at Autos of Chicago Right Now

For buyers specifically looking for lower-mileage certified pre-owned vehicles in the Chicago area, here is a sample of what is currently on our lot:

Is 100,000 Miles Too Many on a Used Car in 2026?

Not necessarily, and this is where a lot of buyers in Arlington Heights, Schaumburg, and Naperville get it wrong. The old rule that 100,000 miles meant a car was done simply does not apply to modern vehicles.

Today's cars — especially luxury brands like BMW, Mercedes-Benz, Audi, Lexus, and Toyota — are engineered to last 150,000 to 200,000 miles or more when properly maintained. The shift to synthetic oils, advanced materials, and more sophisticated engineering has fundamentally changed what a high-mileage vehicle means in 2026.

What matters far more than the number on the odometer is the answer to these questions:

Was the oil changed regularly? Are there complete service records? Has the car been driven primarily on highways or in stop-and-go city traffic? How many previous owners has it had? Has it ever been in a flood or major accident?

A 2019 Mercedes-Benz with 75,000 highway miles and complete service records is a vastly better purchase than a 2021 model with 30,000 miles and zero documented maintenance.

What Mileage Range Is the Sweet Spot for Used Car Buyers?

Most automotive experts and experienced used car buyers agree that the ideal mileage range for a pre-owned vehicle is somewhere between 20,000 and 60,000 miles. Here is why:

In this range, the car has already absorbed the steepest depreciation — typically 20 to 30 percent of its original value in the first one to two years. Major components are still in excellent shape. Most factory warranties or certified pre-owned coverage still applies or recently applied. You are not yet approaching the maintenance milestones where bigger expenses tend to appear.

At Autos of Chicago, the majority of our 450-plus vehicle inventory falls squarely in this range. Most of our cars are 2022 through 2025 model year vehicles with between 15,000 and 55,000 miles — low enough to have plenty of life left, and old enough for the original buyer to have absorbed the depreciation hit.

Highway Miles vs. City Miles: Why It Matters in Chicago

This is a distinction that catches a lot of local buyers off guard. Not all miles are created equal, and in a metro area like Chicago, it matters more than almost anywhere.

Highway miles are generally much easier on a vehicle. The engine runs at a steady, consistent speed. There is less wear on the brakes, transmission, and suspension. Oil circulates properly and components operate at their intended temperatures.

City miles — the kind you rack up grinding through downtown Chicago, sitting on the Kennedy Expressway, or navigating stop-and-go on Route 53 through Palatine — are significantly harder on a vehicle. Constant braking, acceleration from a standstill, idling in traffic, and frequent short trips all add up to more wear per mile than highway driving.

So a car with 70,000 mostly highway miles from a buyer who commuted from Schaumburg to O'Hare every day may actually be in better shape than one with 40,000 miles accumulated entirely through daily city driving in Chicago.

What to Look for Beyond the Odometer

Mileage is a starting point, not a conclusion. When evaluating any used car in the Chicago area, here is what our team at Autos of Chicago recommends looking at alongside the odometer reading:

Service records are the most important factor. A car with consistent oil changes, scheduled maintenance, and documented repairs is worth considerably more than one with a clean exterior and missing paperwork.

Vehicle history reports tell you whether the car has been in accidents, had a flood title, been through multiple owners, or had any odometer inconsistencies. Always request one.

The condition of interior wear points like the driver's seat, steering wheel, brake pedal, and gear shifter can tell you more than the odometer in many cases. If a car supposedly has 40,000 miles but the driver's seat is completely worn through, something does not add up.

A pre-purchase inspection by a certified mechanic is always worthwhile on any higher-mileage vehicle, regardless of how clean the history report looks.

The Bottom Line on Mileage

There is no single number that defines too many miles on a used car. What matters is the combination of mileage, age, maintenance history, brand reliability, and how the vehicle was driven and cared for over its life.

At Autos of Chicago, every vehicle on our lot — regardless of mileage — has been thoroughly inspected and reconditioned by our certified technicians before we put it up for sale. We also provide full vehicle history reports on every car. If something does not meet our standards, it does not make it onto our lot. That is not a policy we bend.

Whether you are looking for something with under 10,000 miles or comfortable buying a well-maintained vehicle closer to 80,000, we have options across that entire range — and a team that will give you straight answers without the pressure.
