Buyers shopping for a used truck or SUV face a basic question: will this vehicle last? According to successive annual studies by automotive research firm iSeeCars, the answer depends heavily on the nameplate. The five vehicles most likely to reach 250,000 miles are all Toyotas, per a 2024 study reported by Car and Driver. The Toyota Tundra sits at the top of the list, with a probability of reaching that milestone roughly four times higher than the overall average. Yet the exact size of that average keeps shifting between study years, and the federal data needed to independently verify any longevity claim has significant blind spots.
Why the 250,000-mile threshold matters for buyers right now
New-vehicle transaction prices have stayed elevated since 2022, pushing more buyers toward high-mileage used models. That makes the question of which vehicles reliably survive past 200,000 or 250,000 miles a financial one, not just a mechanical curiosity. A truck that holds together for a quarter-million miles can offset years of loan payments; one that fails at 180,000 becomes a costly replacement cycle.
The iSeeCars studies attempt to quantify survival odds by analyzing millions of vehicle sales records and their odometer readings at the point of sale. According to one analysis of the research, the firm examined over 260 million vehicles sold between 2012 and 2022 in one iteration of the study. The sheer sample size gives the rankings statistical weight, but it also introduces questions about what the data actually measures. A vehicle that accumulates fewer miles per year, perhaps because it serves as a weekend hauler rather than a daily commuter, will look “durable” in a survival analysis even if its mechanical quality is no better than a sedan driven twice as far annually.
Federal mileage data from the FHWA’s Highway Statistics Table VM‑1 tracks aggregate vehicle-miles traveled across the country but does not break those totals down by make or model. That gap means there is no public federal dataset that can confirm whether top-ranked trucks like the Tundra survive because they are built to last or because their owners simply drive them less each year. The hypothesis that lower annual mileage accumulation, rather than superior engineering alone, explains some of the survival advantage remains plausible but untestable with available government data.
Toyota’s dominance and the shifting odds across study years
The 2024 iSeeCars study found that the Toyota Tundra has an estimated 36.6% chance of reaching 250,000 miles, according to reporting that summarized the latest results. That same study pegged the average vehicle’s odds at 8.6%, or roughly 1 in 12. The five vehicles most likely to reach 250,000 miles in the 2024 rankings are all Toyotas, according to Car and Driver’s coverage of the list.
Those numbers, however, do not sit neatly alongside figures from other iSeeCars study cycles. An earlier version of the analysis placed the overall average chance of exceeding 250,000 miles at 11.8%. A still more recent 2025 edition of the study, published on the iSeeCars website, lists the overall average probability at just 4.8%. The three figures, 11.8%, 8.6%, and 4.8%, come from different study years and likely reflect changes in methodology, sample windows, or how “probability” is defined. Readers comparing rankings across years should treat each edition as a standalone snapshot rather than a continuous trend line.
The direction of the shift is notable. If the overall average has genuinely dropped from 11.8% to 4.8% over successive studies, it could mean that newer model years in the sample are less likely to survive to high mileage, or that the analytical method has been tightened to exclude borderline cases. iSeeCars has not published a detailed reconciliation of these year-over-year differences, leaving shoppers to interpret the numbers largely on their own.
Odometer data gaps and what buyers still cannot verify
Every longevity study built on used-car sales records depends on accurate odometer readings. The National Highway Traffic Safety Administration has documented the problem of odometer fraud for decades, estimating that a meaningful number of vehicles are sold each year with falsified mileage. Even if the true fraud rate is relatively low, any systematic under-reporting of miles would bias survival estimates upward, making vehicles appear more durable than they are in reality.
There are also structural gaps in how odometer readings enter the record. Many states collect mileage at annual inspections or during title transfers, but the rules vary widely, and there is no single national database that tracks every vehicle’s mileage year by year. Vehicles that spend much of their life in states with lax reporting requirements, or that change hands through private sales without meticulous paperwork, may never generate the kind of verifiable data that a researcher would ideally want.
Because iSeeCars relies on odometer readings at the time of sale, the dataset is inherently skewed toward vehicles that are actually being sold, not those that quietly continue in service. A truck that stays with its original owner for 20 years and 300,000 miles without ever entering the used market will not appear in the sales-based analysis at all. Conversely, a model that is frequently traded at 150,000 miles will show a dense cluster of mid-mileage data points, potentially making it look less likely to reach 250,000 miles even if a subset of owners do keep it that long.
How shoppers can use longevity rankings without over-trusting them
For buyers, the practical question is how to turn these high-mileage probabilities into useful shopping decisions. One reasonable approach is to treat the rankings as a rough risk map rather than a precise forecast. If a particular truck or SUV consistently appears near the top of multiple study years, that pattern suggests a real durability advantage, even if the exact percentage odds fluctuate with methodology changes.
At the same time, shoppers should weigh factors that the iSeeCars analysis cannot fully capture. Maintenance history, accident records, climate exposure, and prior usage (commercial versus personal, towing versus light commuting) all have outsized effects on whether a specific vehicle will survive another 100,000 miles. A meticulously maintained truck from the middle of the longevity rankings may be a safer bet than a neglected top-ranked model with spotty service records.
Financing and ownership plans matter as well. A buyer intending to keep a vehicle for only five years may not benefit much from the statistical edge of a model that is slightly more likely to hit 250,000 miles. By contrast, someone planning to drive a truck into the ground over a decade or more has a stronger incentive to prioritize nameplates with a documented track record of high-mileage survival.
Shoppers who want to follow future iterations of the iSeeCars research can monitor coverage through automotive and business outlets or sign up for recurring briefings from news publishers. Some readers subscribe to email updates that flag new data-heavy reports on vehicles and ownership costs, using those summaries as a periodic check on how their preferred models are performing in the broader marketplace.
The bottom line on 250,000-mile claims
Longevity rankings built from hundreds of millions of used-vehicle transactions offer a valuable, if imperfect, window into which trucks and SUVs tend to last. The current research points strongly toward Toyota’s full-size and midsize trucks as standouts, with the Tundra in particular showing survival odds far above the fleetwide average. Yet shifting probability figures across study years, gaps in odometer reporting, and the absence of model-specific federal mileage data all limit how precisely buyers can interpret any single percentage.
For now, the most defensible way to use these studies is as one layer in a broader due-diligence process. Treat a high ranking as a positive signal about a vehicle’s underlying durability, then corroborate it with a pre-purchase inspection, a careful review of maintenance records, and realistic expectations about how you will use the truck. A nameplate’s statistical edge can tilt the odds in your favor, but the difference between a 5% and a 35% chance of hitting 250,000 miles ultimately plays out one vehicle at a time, in the hands of individual owners who decide how-and how much-to drive and maintain their machines.
