No available evidence establishes that these 16 SUVs will reach 500,000 miles, or guarantees that any individual vehicle will. Published longevity studies instead identify models with strong high-mileage histories or estimate odds at lower thresholds; Toyota Sequoia, Toyota Land Cruiser, Lexus GX, Chevrolet Suburban, and Ford Expedition are candidates to investigate, not promises of half a million miles.
For a used SUV, the specific vehicle’s service records, inspection results, condition, and past use matter more to a purchase decision than a model’s reputation. Treat 500,000 miles as an exceptional possibility that depends on the vehicle and its ownership, not a predictable outcome.
What longevity studies can—and cannot—tell you
iSeeCars’ lifespan study analyzes more than two million vehicles produced and sold for at least 10 of the past 20 model years. Its findings describe vehicles in the study population; they do not certify that a particular SUV will reach a given mileage.
Some published figures concern modeled chances of reaching 200,000 or 250,000 miles. Those thresholds are far below 500,000 miles. They cannot be presented as the probability of reaching half a million miles, and they are not proof that any specific vehicle has done so.

Five SUVs worth investigating
The research supports treating these models as candidates to investigate based on reported longevity analysis—not as a ranked list of SUVs proven to reach 500,000 miles. Check the exact model year and the condition of the vehicle you are considering.
Rank #2
- 110 Sheets Log Book: This vehicle maintenance log book includes 110 record sheets to track repairs, services, fuel costs, and other vehicle-related expenses. It also comes with 36 convenient “Service Due” stickers to help remind you of upcoming maintenance schedules. Everything you need to keep your car records organized in one place.
- Detailed Information: Each page is carefully structured with dedicated sections for date, mileage, service description, parts replaced, vehicle information, cost, and additional notes. The clear and organized format allows you to maintain accurate records, monitor repair history, and better manage long-term vehicle performance and expenses.
- Enough Writing Space: The record sheets provide ample space for clear and thorough entries. Whether you’re documenting routine oil changes or major repairs, there’s plenty of room to write detailed information without feeling cramped.
- Easy to Use: The spiral binding allows the notebook to lay flat for comfortable writing, making entries quick and convenient.

| SUV | Evidence in the cited research | Shopping takeaway |
|---|---|---|
| Toyota Sequoia | iSeeCars identifies it among the leading models by highest mileage achieved in its lifespan analysis; its 2025 study gives a 39.1% predicted chance of reaching 250,000 miles. | A candidate to research further, not a promise of 500,000 miles. |
| Toyota Land Cruiser | Identified among leading models by highest mileage achieved in the lifespan study and ranked first in iSeeCars’ 2026 large-SUV reliability page. | Compare the specific vehicle’s records and condition; category or population results do not predict one vehicle’s future. |
| Lexus GX | Its 2025 modeled chance of reaching 250,000 miles is 18.3%; a separate GX 460 estimate is 53.8% for at least 200,000 miles. | Keep the model, variant, mileage threshold, and study result distinct when comparing examples. |
| Chevrolet Suburban | Listed among high-mileage SUVs in the iSeeCars lifespan study. | Use the listing as a reason to investigate, not evidence that an individual Suburban will reach 500,000 miles. |
| Ford Expedition | Listed among high-mileage SUVs in the iSeeCars lifespan study. | Check the specific model year, service history, inspection findings, and use. |
These sources do not support a defensible ranking of 16 SUVs by verified 500,000-mile capability. Other models in the original list may have individual high-mileage examples, but this research does not establish a comparable model-specific outcome for them.
How to evaluate a used SUV for long-term ownership
A model’s place in a longevity study is only background information. Before buying, assess the individual vehicle. These are practical evaluation steps, not measured findings from the cited studies.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errors- Review the records. Look for a consistent service history and documentation of repairs. Ask about gaps and major work rather than assuming a reputation substitutes for records.
- Get an independent inspection. Have a qualified mechanic assess the engine, transmission, drivetrain, brakes, suspension, and overall condition before purchase.
- Check for corrosion and damage. Ask the inspector to examine structural areas and components that may be affected by rust, prior collision repairs, or harsh use.
- Match the vehicle to your needs. Consider how it was used, its present condition, and whether its maintenance and operating costs make sense for your plans.
- Compare like with like. Check the exact model year and variant, and do not treat a statistic at 200,000 or 250,000 miles as evidence about 500,000 miles.
FAQ
Can any SUV be guaranteed to reach 500,000 miles?
No. The cited research does not establish a guarantee for any model or individual vehicle. A particular SUV’s future depends on its condition, maintenance, use, and other factors.
Which SUVs does the research support investigating?
The dossier identifies the Toyota Sequoia, Toyota Land Cruiser, Lexus GX, Chevrolet Suburban, and Ford Expedition as candidates to investigate. That is not a claim that each will reach 500,000 miles.

Does a 250,000-mile statistic tell me the chance of reaching 500,000?
No. A modeled chance of reaching 250,000 miles is a result for that threshold, not a probability of reaching 500,000 miles. Do not substitute one for the other.
What matters most when buying a used high-mileage SUV?
Review the individual vehicle’s service records, have it inspected, check its condition and history, and consider how it was used. A population-level model ranking cannot replace that evaluation.
