Building a cheap van for going to trackdays

Since moving my trackbike to the circuit and back is always a hassle(Not owning a car does not help). So a friend of me and I decided to get an old van to transport the motorcycles to the track. Because of Dutch tax laws we are looking for a old diesel van from before 1978 (Probably a Mercedes-Benz 406 or 408) Just wondering if you guys have some tips what to look out for and what changes to make to such a vehicle? via /r/Trackdays https://www.reddit.com/r/Trackdays/comments/98yyo1/building_a_cheap_van_for_going_to_trackdays/?utm_source=ifttt
