I won this car in an auction lot, and it is brand new, but whoever sent it to auction didn’t use the original Styrofoam inserts - the box was stuffed with newspaper, bubble wrap, old plastic bags, etc.
The spare couplers are included, and the box has the original document with the parts info.
As you can see, it is in almost perfect condition. Price is $75, plus shipping. Paypal or check preferred.
