There's nothing wrong with keeping it for sentimental reasons. It doesn't have to be fixed for that. I have two Electrolux canisters that I lucked out on and are in very good shape. A 1993 Ultralux Classic and a 1987 Marquis. Both need hoses but otherwise are close to new condition.
I won't use them and are part of my decor.
There are people who have put on display record collections, old bikes, old furniture, horse saddles, even old cars. Who hasn't seen an old wringer washer on someone's lawn as part of the landscape with the tub filled with flowers.
I have retro working miniature christmas lights year round, the occasional vacuum, and retro 70s/80s decor.
