[OXO cube]

looks to me like the courier vehicle has been involved in a road traffic accident 
and is the reason not everything is there
hopefully no one was hurt 
but i do think DPD should at least have let someone know  

as another thought :-
Graham , you have all the host's addresses and contact info 
and i don't think i only speak for myself 
but i would happily transport the cars ( at my own cost ) to any other host locally 
when i say locally i mean 30-40 mile radius 
further distances could be a 'meet in the middle' scenario ( but not the Irish sea )
tbh it would be nice to personally meet some of the other hosts over a cuppa at a café 
that could reduce having to use a courier to only once or twice during the whole event
