Feel free to list them in our forum. Just be sure to include an asking price.
I know what you mean about re-selling them, eveyones looking for a deal. When you pay say $50 for an Action die cast car the season it comes out, and then you can find the same car at the track next season for $10, or even less, it really kills your resale value of these cars. Good luck selling them though.
I have about 2000 die cast nascar cars myself, 1/64. 1/32, a lot of 1/24, and some 1/18 sacle. I have autographed cars by John Force, Kenny Bernstein, Al Hoffman, Jeff Gordon, Joe Nemechek, and a few others. I have autographed signs, hats, posters and other misc. autographed items. I have hand signed items by Dale Earnhardt, Richard Petty, Mark Martin, and many more. I also have several pieces of raced used, and crashed sheetmetal. I have enough Nascar poop to fill a 15x15 room or more. Not to mention about 1500 hot wheels cars.
