Car longevity is of interest to many car owners and concerns several things: maximum service life in either mileage or time (duration), relationship of components to this lifespan, identification of factors that might afford control in extending the lifespan. Barring an accidental end to the lifespan, a car would have a life constrained by the earliest part to fail. Some have argued that rust and other factors related to the body of a car are the prime limits to extended longevity.
An automobile is a highly engineered collection of complex components, each of which has its own lifespan and longevity characteristics. The MTBF (mean time between failures) of some components is expected to be smaller than the life of the car, as the replacement of these is considered part of regular maintenance. Other components, which typically experience less wear, are expected to have a longer life; however, a large longevity may very well require replacement of several of these, raising issues of economics. The most expensive part of an electric car built in the 2020s is the battery, and its lifetime is expected to be about 16 years, or about 2 million kilometres (1.2 million miles) if the car driven a lot.
The motivation for pursuing longevity can vary. The economic trade-off of the remaining value versus repair cost is usually considered when deciding to repair or discard. Other factors, such as emotional attachment or a desire to reduce waste, may also be involved.
The life of the auto, as the collection, follows, according to a very common model, a bathtub-like pattern. After an initial phase, where failure because of design and manufacturing defects as opposed to wear-out, is more likely (hence the offering of the warranties by the manufacturer), there may be a long period of unlikely failure. The maximum lifespan and future value as a classic for any car are typically not known when the car is purchased. Research into longevity of vehicles will improve the ability to predict car life, with such things as a life table for cars.
In the United States, the Environmental Protection Agency assumes the typical car is driven 24,000 kilometres (15,000 miles) per year. According to the New York Times, in the 1960s and 1970s, the typical car reached its end of life around 161,000 kilometres (100,000 miles), but due to manufacturing improvements in the 2000s, such as tighter tolerances and better anti-corrosion coatings, the typical car lasts closer to 322,000 kilometres (200,000 miles).

In a public economics sense, Kasmer[who?] argues that retrofitting autos with a newer transmission would extend the lifespan while at the same time increase fuel efficiency, reduce carbon emissions, and prevent the sudden influx of discarded vehicles into the waste bin as cars are junked to be replaced by a modern vehicle. However, with replacement parts for modern cars becoming ever more high tech, expensive and proprietary and therefore difficult to obtain (due to OEM copyright), many critical components are no longer available at low cost from third party aftermarket suppliers. Due to this fact, most modern cars can no longer be maintained once repair cost of the car exceed resale value. This trend has led to the modern cars being labeled as the first ever "disposable" cars.
Notable examples of high mileage
Some car manufacturers support a "high mileage" club. For example, Volvo and Mercedes-Benz have a "High Mileage Award" program in which owners who drive 250,000, 500,000, 750,000, and 1 million kilometres (156,000, 311,000, 466,000, 622,000 miles) are awarded with a certificate and a radiator grille badge.
Many non-commercial vehicles (both auto and truck) have exceeded 1,610,000 kilometres (1,000,000 miles). For instance, in 2013, East Patchogue, New York resident Irv Gordon (1940-2018) had accumulated 4.82 million kilometres (3 million miles) in his 1966 Volvo P1800. The car had amassed 5.15 million kilometres (3.2 million miles) by Gordon's death on 15 November 2018.
In 2006, a 1995 Dodge Ram was reported to Chrysler as having gone 1.61 million kilometres (1 million miles).
A 1989 Saab 900 SPG belonging to Peter Gilbert of Wisconsin had put in 1,611,573 kilometres (1,001,385 miles) before it was donated to the Wisconsin Automotive Museum.
