Irv Gordon's Guinness World Record Volvo tops it, followed by a 1976 Mercedes-Benz 240 D that spent its life as a Greek taxi and crossed nearly 2.86 million miles — one of two Mercedes models in the top 10, alongside a 1966 250 SE that reached 1.28 million miles under a single owner. Rounding out the list: a Finnish company-fleet Volvo 245 GL wagon at 1.63 million miles, a Montreal taxi's 1963 Plymouth Fury that came heartbreakingly close to a Guinness record before a collision ended its run at 1.62 million, and a 1963 Volkswagen Beetle that hit 1.61 million miles on the strength of multiple swapped-in engines and transmissions rather than any single original drivetrain.The Common Thread Isn't The BadgeWhat stands out reading through all ten — which also include a highway-heavy 1983 Lincoln Town Car, a delivery-route 1991 Chevrolet Silverado, a Ford F-250 that needed two full engine swaps to reach 1.2 million miles in just five years of hard commercial use, and a 1990 Honda Accord that earned its owner a factory-sponsored parade — is how little separates them mechanically. CarGurus' analysis points to four habits shared across nearly every entry: fixing small problems before they become expensive ones, driving smoothly rather than aggressively, keeping the car in near-constant use rather than letting it sit idle, and accepting that major components will eventually need replacing. None of these cars are original down to the drivetrain. Longevity on this scale isn't about a car surviving untouched — it's about an owner willing to keep rebuilding the same car indefinitely.Reliability Then Isn't Reliability NowToyotaIt's worth separating the legend from the modern buying decision. The 240 D's reputation rests on 1970s diesel simplicity — a mechanically basic engine with few components to fail — and that same brand today ranks last among German luxury automakers in Consumer Reports' 2026 rankings, a reminder that decades-old durability legends don't automatically transfer to a modern lineup built on entirely different engineering. For buyers actually shopping on long-term durability today, Toyota's current models dominate the data the way taxis and delivery trucks dominate this list of all-time outliers.AdvertisementAdvertisementMercedes-Benz has leaned into its own history here, officially awarding mileage badges to owners who hit milestones between 155,000 and 1,000,000 miles — a tacit admission that the 240 D's reputation is still doing marketing work decades later. It doesn't change the math for anyone cross-shopping a 2027 model, but it explains why a 50-year-old diesel taxi still gets cited as a reliability benchmark whenever this conversation comes up. As for modern cars across the globe, they are incredibly complex, with thousands of computers and lower-quality materials, making the investment in maintenance seem pointless. It's easier to replace your vehicle with a new one, and that is exactly what they want. Profits cannot grow if people do not buy new vehicles, and the firm's stakeholders will be unhappy.This story was originally published by Autoblog on Sep 2, 2026, where it first appeared in the Features section.
