1/6 Black Greer Purdome Slingshot dragster with optional case from RAR. I am calling it rare because I have never seen one for sale in the aftermarket. I have NO BOX for this. The model cost $1799 new and the case was $299 any suggestions on pricing? Next I have a Ferrari 250 GTO by Bell in 1/5 scale which came in crate. It is not perfect but very nice. I have a GMP 250 GTO engine in 1/6 scale to sell with it for additional cost. The car was $4995 and the engine was $299 new. I have no idea how to price these, any suggestions please.Email me at joshj5621@gmail.com
