It's not cheap, but this 1978 Volkswagen Beetle Jubilee Edition is a one of a kind. According to the seller, it's the last-ever original VW Beetle built for the UK market.
Here's the story. In 1978, the last 300 Beetles were built for the UK market, each one labelled and numbered to that effect. Number one was kept in a museum on Germany. This is number 300, the very last one.
