Top 10 most-expensive models
The rear-loading Volkswagen Microbus Beach Bomb was an unreleased prototype. Its extreme rarity meant we were unable to secure a photo for this project, explaining its omission on the project page.
The most recent valuation stands at £80,000 to £120,000. Rear-loading was unique to this Beach Bomb, which is what makes it so rare. This model was never released because its high centre of gravity made it prone to falling off the track.
