Updating:
"They remarked that every one looked like it was frozen in time, the 1970s. All very well-maintained, but in drastic need of updating."
Ah, that dread word, "updating," sometimes expressed as "dated," usually by a Realtor. I personally do not understand why a well-maintained house should need updating for the purposes of making it look more in line with current fashion. I have seen many a dynamite midcentury kitchen ruthlessly ripped out, its high-quality fittings tossed in a Dumpster or nearly given away on Craigslist so that they might be replaced with today's chipboard cabinets and weird-science appliances. The result usually looks out of place; no one had granite countertops and foofy carved cabinetry back in the day.
A well-maintained vintage kitchen or bath is usually much easier to live with and care for than today's "designer" extravaganzas. What I really don't understand is that today's home buyers often profess to be interested in historic styles and periods, but when it comes to actually living with yesteryear's amenities - well, most people today consider themselves muuuuuuuuuch too good to live with the shame of Formica countertops or a bathroom that someone else - horrors! - has actually made use of before them.
Ah, well. Let the rest of the world discard nice things for the sake of fleeting fashion if it wants to. Nearly everything I own is something that someone else did not want any more, and every bit of it is of a quality level that is all but unobtainable today.
