Pre-owned. Had these all together in storage. I did my best to list them out below. They were played with and have varying conditions. The ones I personally think have the most wear can be seen in photos of individual cars (paint chipping, loose wheels, scuffs).  The only one I see with a missing part is the match box big banger is missing engine (last photo).  43 in total.
