Just looking at where you've measured the tyre depth on that first pic. It's on the wear marker , some one correct me if I'm wrong but I think you could add a least 1.6mm on to your measurement as to total depth of tread. Might help with the sale.
The thin mat will be the original OEM basic one , mines also like that albeit in my 350z. The thicker one with the logo would of been an optional extra.
Also these from the same seller. Seems to be a Nissan dealership.

Best bet for a bonnet is a new one direct from Nissan at about £300, youll struggle to get second hand. As your wrapping may be best to just get a carbon one.
