Find a fair price on a VW microbus by searching on sites such as eBay.com, AutoTraderClassics.com, ClassicCars.com and TheSamba.com to compare prices among different years. Microbuses from certain model years are worth more than others, especially based on condition and whether or not they include all of their original parts.
Buses manufactured between 1949 and 1962 are part of the initial VW series and typically cost more than newer models, especially if they are in original condition, rather than having been restored. If you are looking at one of these models, make sure to find out if it has all of its original parts or if it has been refurbished with later model parts, in order to make sure that it is priced accordingly. A microbus with several non-standard parts should be priced several thousand dollars lower than a factory-original model.
It is also important to inspect the general condition of the bus, as any internal or mechanical issues should merit a lower price. Even if the bus has all of its original components, if the engine needs extensive repairs or the interior is torn and frayed, you should use these as bargaining points to negotiate a lower price or walk away from an overpriced listing.
