I Asked ChatGPT Which Used Car Brands Cost the Least To Own After 100K Miles — Here's What It Said
In an ideal world, you and your used car would be in it for the long haul, racking up miles without racking up costly repair bills. Thanks to your car's long-term reliability, you'll save on the cost of replacing it and avoid frequent trips to the repair shop — even after it hits 100,000 miles. You just need to know which used cars are worth looking into.
If I were doing a detailed search for a used car that wouldn't drain my finances after 100,000 miles, I'd ask a car buff in my life or consult a mechanic. But to kick off that search, I'd likely turn to ChatGPT. I asked the AI to tell me which used car brands cost the least to own after they reach 100,000 miles.
Toyota
ChatGPT had high praise for Toyota. The AI said Toyotas were comparatively inexpensive to own because their engines and transmissions often exceed 200,000 miles with routine maintenance.
Even when you do need repairs, ChatGPT said you can expect parts to be "plentiful and relatively inexpensive." To make the process easier, independent mechanics are generally familiar with Toyota repairs. ChatGPT added that "major repairs are less common than with most competitors."
Honda
The AI also found Honda to be a solid bet for someone searching for a used car that could go the distance financially. ChatGPT cited long-lasting powertrains, low maintenance costs and excellent fuel economy.
"Strong resale value offsets ownership costs," the AI wrote.
Mazda
Why did ChatGPT include Mazda on its list of used car brands that cost the least to own after 100,000 miles? The AI said the brand has demonstrated "excellent reliability since the mid-2010s."
In addition, ChatGPT praised Mazda's naturally aspirated engines because they generally require less expensive maintenance than turbocharged competitors. The AI also noted there are "fewer major drivetrain failures than many rivals."
Lexus
Are you surprised to see a luxury brand on this list? ChatGPT understood that and preemptively shared its reasoning, noting that Lexus vehicles:
Share many components with Toyota
Have a reputation for outstanding reliability
Require fewer repairs than many luxury competitors
"Maintenance is more expensive than Toyota's, but significantly less than many European luxury brands," the AI wrote.
Subaru
ChatGPT said newer Subaru models have durable boxer engines. The AI was also taken with the way the brand's standard all-wheel drive reduces the need to upgrade, making the vehicles well suited for winter climates. Additionally, replacement parts are generally easy to find.
However, ChatGPT did add a key caveat.
"Models from roughly 2012-2014 are more prone to oil consumption issues, so later model years tend to be safer bets," the AI said.
Finding a Car That Suits Your Preferences
Though ChatGPT presented its assessments of the durability and cost-effectiveness of its top picks, it also acknowledged that personal preferences can help guide your purchase. The AI also offered more nuanced advice based on buyers' priorities.
"For buyers focused on minimizing total ownership costs after 100,000 miles, a well-maintained Toyota or Honda remains the benchmark," ChatGPT wrote. "If you're willing to pay a bit more upfront for a luxury vehicle with lower long-term repair risk, Lexus is often the standout choice. Meanwhile, Mazda offers one of the best combinations of driving enjoyment, reliability and affordable maintenance."
The Bottom Line
While you'll likely want to consult a car expert and do additional research, using ChatGPT can provide a useful starting point for narrowing your options.
The AI supplied a list of reliable used car brands that can be comparatively inexpensive to own once they hit the 100,000-mile mark, and those recommendations could help guide your search for a dependable used vehicle.
