Inspired by posts about cars people wish they still had, I found a photo of my 1962 Mercedes-Benz 220, a possession I should have kept for a lot of reasons — including the fact it would have been a good investment.

But then, remorse over cast-away treasures is a common experience as we age. Sometimes we discover such articles in a sock drawer, or hidden on a shelf, joyful we didn’t discard them after all. That won’t happen with the car — I distinctly remember selling it to a nurse who worked at Deaconess Hospital.

I had bought it from my girlfriend’s older sister in 1971, for $600. It cost $3500 new, and was only nine years old. Although afflicted with a slipping clutch, I thought it was a bargain. That said, I was in college, too poor to be an auto enthusiast, too dumb not to be.
