A CarFax report is nice. But it's also easy to fake, easy to miss things, and easy to trust too much.
I've seen clean CarFax reports on cars that were clearly wrecked. I've seen "one owner" cars that changed hands three times. I've seen "no accidents" on vehicles that had obvious panel gaps you could fit your thumb through.
The CarFax tells a story. But the car itself tells the truth.
Here are three places I look before I even ask to see the report. They've never lied to me.
1. The Tires
Tires are a confession. They tell you how the car was driven and how it was maintained.
What I look for:
Mismatched brands. Different tires on different corners means the owner replaced tires one at a time. That's what you do when you're broke or don't care. Neither is a good sign for the rest of the maintenance.
Different tread depths. A new tire on the left front and a bald tire on the right front? The owner didn't rotate them. Or they hit something and only replaced the damaged one. Either way, they weren't paying attention.
Inside edge wear. Run your hand along the inside edge of the front tires. If it's feathered, cupped, or worn more than the outside, the alignment is off. That could be normal wear. Or it could mean the car hit a curb hard enough to bend something.
Cheap brands. LingLong, Westlake, Douglas, anything with a name that sounds like a kung fu movie. If the owner put the cheapest tires possible on the car, what else did they cheap out on?
What a clean set tells me: Matching brand, even wear, reasonable tread depth, name-brand tires. This owner cared. The car was maintained.
2. The Seat Bolsters
The driver's seat tells you exactly how someone got in and out of this car. And how many times.
What I look for:
Worn outer bolster. The left side of the driver's seat (in left-drive markets) takes the most abuse. Every time someone gets in, they slide across it. Every time they get out, they grind into it.
A little wear is normal at 60,000 miles. A lot of wear at 30,000 miles means the owner was heavy, wore jeans with rivets, or both. Not a dealbreaker. But a clue.
Cracked or torn leather. Leather that's cracking at 50,000 miles? The car sat in the sun without care. The owner didn't condition it. They probably didn't maintain other things either.
Worn cloth on the wrong side. If the seatback bolster is worn (not the bottom), the owner was sliding sideways into the car. That's weird. That's also how people with bad hips or injuries get in. Not a red flag, but ask questions.
What a clean seat tells me: The owner was careful getting in and out. They didn't drag themselves across the seat. That same care probably applied to how they drove and maintained the car.
3. The Steering Wheel
The steering wheel is a diary of every drive. It records how the owner held the wheel, where they drove, and how much they cared.
What I look for:
Shiny spots at 10 and 2 (or 9 and 3). That's where most people put their hands. A little shine is normal at 40,000 miles. A lot of shine means highway driving (hands in the same position for hours) or nervous grip. Not a red flag alone.
Wear at the top. Someone who drives with one hand at noon is either relaxed or lazy. Usually fine. But if the top is worn but the sides are pristine? The owner drove like this all the time. That's unusual.
Peeling or sticky leather. This is a big one. Leather that's peeling or turning sticky means the owner had acidic sweat or used harsh cleaners. It also means they didn't condition the wheel. If they neglected the thing they touched every drive, what did they neglect under the hood?
Wear on the back of the wheel. This is weird. Most people don't touch the back. If the back is worn, the owner drove with their hands at 10 and 4 or had an unusual grip. Probably fine. But worth noting.
What a clean wheel tells me: The owner's hands were clean, dry, and gentle. They probably treated the car with the same respect.
Putting It All Together
One sign alone doesn't mean much. Mismatched tires could be bad luck. Worn seat bolsters could be a heavy uncle. A shiny steering wheel could be from hand lotion.
But when you see all three together? That's a pattern.
Bad tires + worn seat + shiny wheel = The owner didn't care. Walk away.
Good tires + clean seat + clean wheel = The owner cared. This is a good bet.
Mixed signals = Look closer. Maybe the owner cared about some things but not others. Check the service records.
The CarFax Still Matters (A Little)

I'm not saying ignore the CarFax. It catches flood titles, salvage brands, and odometer rollbacks. That's useful.
But the CarFax won't tell you that the owner dragged their jeans across the seat 50,000 times. It won't tell you they ran mismatched tires for 20,000 miles. It won't tell you they drove with a death grip for three years.
The car tells you that. If you know where to look.
So before you ask for the report, spend five minutes with the tires, the seat, and the wheel.
They've never lied to me.
And they're not about to start.
If the deal sounds clean, look for where they buried the dirt.
