Volkswagen

Volkswagen built the most-produced car in history — over 21 million Beetles — and with it a collecting culture unlike any other: split-window and oval-window Beetles, Type 2 buses whose 23-window Sambas trade at six figures, and the Karmann Ghia's affordable elegance. The Golf GTI of 1976 invented the hot hatch and its Mk1 generation is now firmly collectable. Today's VW is a giant navigating the electric transition, with the ID. Buzz consciously mining the heritage — but the air-cooled era remains the heart of the collector story, sustained by the largest classic parts and club ecosystem in the world.
