This kit is new in box. I bought it in 2009, see pic below.
As you can see it is still factory wrapped and in like new condition.
Due to the size and weight the shipping from USPS will likely be in the $30 range. It is 24lbs and the box size is 19 x29 x 3.5 inches, leaving the 48706 zip. I would also be willing to arrange for pickup locally.
Here is the link to the kit information on the Real Good toys website. It has been stored in a smoke free home, laying flat, and in an air conditioned room. Please contact me via email, my address is located near the top right of the page. Thanks in advance
