As I may have mentioned before, men should give their fiancees an exotic and rare speed part instead of an engagement ring or a wedding ring. It will have a lot more value in the event of a divorce when it comes time to sell the part compared to a diamond. "Honey, in a demonstration of my 'luv' for you, I give you this vintage mechanical Hilborn fuel injection system." Clunk! As he lays it on the table. "Oh honey, you shouldn't have." And she shows it off to her girlfriends. Maybe this does happen...in a parallel universe. Or another dimension.
