@Leoz: and think about that, that cars from the 80ies and older, you can easier repair at home than the actual one with their lost of electronics, fuel injections and so on.

But tell your stepsister, that ALL VW Campers are very expensive to buy, especially in the UK.
I know several VW-Bus-freaks, who are complaining, the the prices are high -too high for the real value of just a VW- and that this is also caused by the popularity of old VW Buses and Campers in the UK! A lot of them, even LHD, were bought and exported by British guys.
