Couple of non-female, non-firearm items immediately come to mind:
My Kubota tractor. Dad bought it new in '78. Had to sell it because of my divorce, in '04. Was moving into an apartment temporarily, and had no place to store it.
My Old Town Tripper canoe. Heavy, but very stable. Never owned another near as nice. Sold it after a shoulder surgery gone bad. I was a bit hasty.
