In the relentless pursuit of perfection, automakers have sometimes gone too far—crafting vehicles so robust, durable, or technically advanced that they became legends of overengineering.
While these cars dazzled with their quality and longevity, their makers often paid the price: sky-high costs, shrinking profit margins, and unforeseen headaches for mechanics and owners alike.

This list explores 20 of the most overbuilt cars ever made, where the drive for innovation and durability clashed dramatically with business realities and practicality.
