Our 1950’s GE wall oven! That thing won’t quit (but new ovens will not fit properly in the existing masonry opening, so ok).
Anything from my parent’s / grandparents was made so much better than now. My mom’s 1960’s KitchenAid mixer still hums. I thought my 1960’s Singer sewing machine would live forever, but alas, last year was it’s last (I’ve had it serviced numerous times, and this time the shop said it couldn’t find the issue).
My late 1800’s mantle clock doesn’t keep current time anymore, but just seeing it brings many memories of visits with my grandmother, so that stays at least as long as I do.
I have some refinished mid-century Kent Coffey dressers from my parents that my DD would love - but they live 2400 miles away, and their new place is so small there’s no room for anything.
