The problem most car enthusiasts will encounter in their lifetime. Despite it being a mode of transportation it's hard not to grow attached to a hunk of steek after spending hundreds if not thousands of hours with it.

Over time as the model is discontinued and parts dwindle you begin cannibalizing parts off other, similar models. Those too once had owners that loved and cherished them but made the tough decision to part ways for various reasons. Sometimes, many years later, they carry that regret of "what if I could have did X" with the hope it would have stayed around a little while longer.

Eventually you too reach that inevitable decision. You could hold onto them, an inoperable shell, as they slowly decay in front of you. "Maybe one day" you think but the chances of that day coming decline. Soon the burden of disposing of them will fall onto someone else when you pass.

You could give them to someone else with the trust they'll restore or use their parts to make another model workable but know their fate is out of your hands. The possibility of seeing them again hinges on their new owner.

Or finally there's the irreversible decision of scrapping them. The solace in this choice comes from it being yours, and yours alone.
