People talking like this is a £50 note found in the street.
These are someone's cars they've obviously deliberately stored in a building on their private land.
All this talk about dibs and going back with a trailer... FFS, if I turn up at your house, see a car in a garage, take some pictures then start with comments about coming back later to take it how would you react?
Somehow the reactions are different when it's your car getting the attention or disappeared on a trailer...
