If you ask your friends what they paid for their new car, many won’t give you the total price. They’ll give you the amount they pay per month.
That’s not a fluke. Research suggests that it’s the whole story of how people purchase cars in 2026 (and maybe it’s always been like this, but it’s getting starker). People aren’t really buying cars anymore. They’re buying a monthly payment.
The price didn’t break. The payment did.
Kelley Blue Book put the average new-vehicle transaction price at $50,562 in September 2026. That’s just below the record of $50,614 set in December 2025. Prices have mostly held steady year over year.
Surprisingly, interest rates have been sitting still, too. Edmunds’ Q3 2026 data on financed new-vehicle purchases shows the average APR held at 7.0%, the same as a year earlier.
At the same time, the average monthly payment in Q3 2026 hit a record $787!
So what changed? The length of the obligation. A record 25.5% of those financed purchases carried loans of 84 months or longer.
That’s seven years or more. Picture the car you’ll be driving in year six. (Some of us drive our cars until they fall apart, so this isn’t difficult.)
Here’s the weird thing: We don’t think buyers are being reckless. They’re doing what the market trained them to do. When the only question anyone asks is “What can you afford a month?” you solve for that number. You stretch the loan until it fits.
The payment outlives the car.
Stretch long enough and the loan stops matching the car. (I hear you, those who buy “used used” cars like I do.)
Edmunds’ Q2 2026 data shows that 29.6% of trade-ins toward new vehicles had negative equity. The average amount underwater was $6,884.
Think about that. Nearly 3 in 10 people trading in a car are still paying off the vehicle they’re about to hand over. Roll that balance into the next loan, and you’re financing yesterday’s car along with today’s.
That’s my read, not a statistic. But it’s hard to look at those numbers and see much else. At some point, the payment stops feeling like a purchase and starts feeling like a subscription you can’t quite cancel.
Happy with the deal. Wary of the dealer.
In Cox Automotive’s 2025 Car Buyer Journey study, an opt-in online panel of recent buyers who used the internet while shopping, 76% of new-vehicle buyers said they were highly satisfied with the buying process. A record. But “online” doesn’t mean the deal happened online.
In the same study, only 7% bought entirely online (lower than what TV ads suggest), 53% did every step in person, and 63% said a mix of online and in-person would be ideal.
Meanwhile, Gallup’s December 2025 poll, a random sample of U.S. adults, found that just 7% rated the honesty and ethics of car salespeople as high or very high.
These are different studies asking different people, so they don’t belong in one equation.
Still, the pattern makes sense if what you’re really buying is a payment. You leave satisfied because the monthly number worked. You stay wary because, deep down, you’re not sure what you actually paid.
A satisfied customer and a trusting customer are not the same thing. From where we sit, most of the industry’s scorecards measure the first one. Future profitability is measured by the second one.
So what?
If you sell anything people pay for by the month, “Did they buy?” is the easy question. The harder one is “Do they understand what they bought, and would they do it again with their eyes open?”
You won’t find that answer in a transaction record. Transactions tell you what happened. People tell you what it felt like and what they’ll do next time. You only hear it if you ask and then actually listen.
That’s the fun discovery work that I love doing at Thrum. The most important number in car buying right now isn’t on any window sticker.
It’s the one people carry around in their heads, every single month.
