Thanks for the information Paul. Very helpful. The NIB mint Countachs seem so rare even information on them is minimal, let alone a sale for a second hand on, but in box....kinda scenario like mine.
My effort will be to establish some sort of pricing guideline, then put her up for a trade on Tamiya Club. Was thinking of offering for a trade for a bruiser of older truck of some sort....?
Thanks again for your time, and yes the foams are a complete set, not worn or cracked but not new in a sealed box.
As well there is a manual for a 1st generation Porshe, as well as the motor assembled. Looks like who-ever had this car had has or had the 959 as well, but some of the items ended up in this box.
