If you sold it to a dealer, no, they would probably find a way to turn it against you
However if you sell privately, then of course yes. Todd, think about all the times you've advised a newbie 911 shopper/owner on this site to hold another ~2K$ in reserve for unforseen fixes. Most of this uncertainty would be addressed with a factory warranty. It would be a selling point for me...but I'm not buyin your A8. Do you want to buy a 99 Land Rover Disco 2 with 4K left on the manufacturers warranty?
