The Volkswagen T25 (known as the T3 in Europe and Vanagon in North America) is one of the most versatile and practical classic Volkswagens ever built. Produced between 1979 and 1992, the T25 combined the traditional rear-engine layout of earlier VW vans with a more modern, spacious body and improved handling.
Today, T25s are highly sought after as campers, family vans and investment vehicles. However, rust, neglected maintenance and poor conversions can quickly turn a bargain into an expensive project.
This guide covers everything you need to know before buying a VW T25/T3.
Before You Start
When buying a T25, condition is far more important than mileage.
A rust-free van with high mileage and a good service history is often a far better purchase than a low-mileage example hiding structural corrosion.
Mechanical parts are generally available, but body restoration costs can quickly exceed the value of the vehicle.
Always inspect the van thoroughly in daylight and never rely solely on photographs.
