VW Bay Window Buying Guide (1967–1979)
The Volkswagen Bay Window is one of the most recognisable classic camper vans ever built. Produced between 1967 and 1979, the Bay Window replaced the Split Screen and introduced a more modern design with a single-piece curved windscreen, improved suspension and better practicality.
Today, Bay Windows remain hugely popular as campers, weekend cruisers and investment vehicles. However, rust, poor restorations and neglected maintenance can quickly turn a dream purchase into an expensive project.
This guide covers everything you need to know before buying a VW Bay Window.
Before You Start
When buying a Bay Window, body condition is far more important than mileage.
A solid, rust-free van with a tired engine is usually a better buy than a shiny van hiding structural corrosion.
Mechanical parts are widely available and relatively straightforward to repair. Body restoration can easily cost tens of thousands of pounds.
Always inspect the van thoroughly and never rely solely on photographs.
