I recently sold TTA 223. I have the original gator back tires that were on the the car for sale. The car had 8,500k on it so they are in good shape. Also I have gold TTA diecast # 40 for sale. If interested in either please PM me.
Mine is 22 by 24. It seems very small with the two cars. But we should have a shed built next year and I will be able to get rid of anything not car related. Also for a floor try race deck. Its easy to clean and your four post lift can sit right on it.
