* Definition of "older": A 1960s Chevy truck is vastly different from a 1990s model, which is different again from a 2000s model. Each generation had its own strengths and weaknesses in terms of reliability. Early trucks were simpler mechanically, meaning fewer things could go wrong, but the parts themselves might be less durable by modern standards. Later models benefited from technological advancements but also incorporated more complex systems prone to their own types of failures.
* Maintenance: Proper and consistent maintenance is crucial for the longevity of any vehicle, regardless of age. Older trucks that have been meticulously maintained can significantly outlast neglected newer trucks.
* Specific model and year: Reliability varied even within a given model year due to manufacturing inconsistencies or specific design flaws present in particular runs.
* Definition of "reliable": What constitutes "reliable" is subjective. An older truck might be considered reliable for basic transportation but unreliable for long trips or heavy hauling. A newer truck might be more reliable in terms of fewer breakdowns but more expensive to repair when something *does* break.
* Rust: Older trucks, particularly those used in climates with heavy snowfall or high humidity, are highly susceptible to rust, which significantly impacts reliability and safety.
In short, it's inaccurate to make a blanket statement. Some older Chevy trucks were extremely reliable, lasting decades with proper care. However, modern Chevy trucks have benefited from advancements in materials, manufacturing processes, and technology leading to improvements in certain areas of reliability. The overall picture is nuanced and depends heavily on the specifics of the individual trucks being compared.
