After looking at the listing, I dont think he was trying to trick anyone, but he should have noted the set was incomplete in the title of the listing. To me, "new" in a way implies that everything is there (we have a huge inventory of brand new cars!! (tires sold seperately)). Sure the condition is indeed new, but this item is in my opinion, new with an asterick. So imo he should have made some sort of note in the item title. I dont think he will have a problem cancelling though, from a sellers pov not worth the hassle of dealing with a potential case, back and forth with the buyer, just cancel, get your fees back, re-list. Thats what I would do anyway.
