Peugeot's Boxer vans have become popular right across Europe. They are well priced, reliable, and have proven engines that are used in a surprising amount of vehicles, including non-Peugeot vehicles.
The Boxer is popular with professional campervan conversion companies, and DIY campervan converters. There are many good examples around for purchase. Parts are well priced and easy to find right across Europe.
Professional converters Murvi use the Boxer as the base for their Meteor campervans.
