Since a number of folks brought up selling off cars and 'thinning' collections in a previous thread, that begs another question. Obviously there are a lot of options such as online auctions, forums (like right here at HRW), giving them to a favorite niece or nephew etc.
What methods or approaches do you prefer when it's time to pass on that one slot car or those many slot cars...? Any methods that just didn't work for you?
