A custom VW dune buggy is a modified Volkswagen Beetle chassis fitted with a fiberglass or metal body, and often powered by a larger engine. Dune buggies were originally designed for use on sand dunes, but have since become popular for off-roading and beach driving.

Custom VW dune buggies offer several benefits over stock Beetles, including increased ground clearance, larger tires, and more powerful engines. These modifications make dune buggies ideal for navigating rough terrain and sandy beaches. Additionally, dune buggies are often equipped with roll cages and other safety features, making them safer than stock Beetles in the event of a rollover.
