I think I'm going to go with Hugh Dancy, all the media of him as Will Graham is just world weary and "IDGAF" enough to be perfect for Car here, lmao!
Car is definitely in the market to be purchased again, he just never had much luck when he was younger, and now he's just a little too old and a little too set in his way for anyone to see him as a good sell - if Nicholas is in the market for a stubborn Helot, it could definitely be something we discuss!
