Drivers and cars has become older today, so most of us don´t drive long distances like before.

Maybe not to recommend, but even a small trailer can take two microcars

 

 

Farmobil with Minicomtesse onboard.

On top of the old Volvo is a electric Sinclair and om the trailer is a Mochet from 1958

This is better! For daily use this trailer carries plastic tubes, but it is big enough for three Messerschmitts.

First time the chairman Anders Johnsson visited Störy in Germany was 1979. That time "cheating" with a Bedford van, but in the next summer this 1955 Messerschmitt used its own wheels to the Messerschmitt rallye in England after a detour to Paris.
Looks strange to tow a microcar aftar another small car.
Maybe the reason was to bring more luggage than a Bond Bug can carry?
Modified caravan for carrying an Isetta.
An old chassis from a caravan can be converted to a tralier for two microcars.
