My husband hates to get rid of things which still work. That's partly why we still own his first vehicle - a 1956 Chevy pickup which he bought while in high school (about 1971). That's the first vehicle I ever saw with a starter button. On the floor, no less!
Talking about keeping things, I still have and ride the banana bike I got at age 7 for Christmas in 1966. Recently restored it and take it with me to display at car shows with my 69 VW.
