The Alfa Romeo AR 8 represents a venture into the commercial vehicle market. These vans were designed for small businesses and offer surprising reliability.
Common issues include rust (especially in floors, sills, and around the suspension mounts). Parts availability will always be a concern, and they may prove challenging to procure.
For WOF inspections, rust is a major concern- these vans probably saw active service. Check the integrity of the suspension, brakes, and chassis. Mechanics will be looking for corrosion and suspension wear.
The AR 8 featured a diesel engine. While these vans are not luxurious, they have surprisingly large cargo capacity. Like any commercial vehicle from this era, maintenance is often neglected, but the vans are rugged.
