I personally don't think it would have hurt to talk to them.. Sure they have no idea how much time and/or money goes into these cars.. Even if it was a $200 dollar POJ they should be told to respect others property.. Tell them to always ask the owner first. Heck he probably would of let them sit inside and take the pics.. I know I would have but ask first..I figure they are just young naive kids.Kids that are the future of this hobby.
