Formats evolve. Just as KUPD had evolved from its original direction to what you heard starting in 1983, Classic Rock has done its share of evolution over its timeline.
Another thing that I believe needs to be pointed out is that at the time AOR became a format descriptor, top-40 stations were often referred to as "rock" stations. AOR was not, as many appear to believe, a version of the progressive rock formats that preceded it. It was hit focused, but without the top-40 presentation. Hence Gino Vanelli being acceptable at a lot of AOR stations. You cannot make a fair comparison between AOR back in the day to Classic Rock today.
Though I will say that the progressive rock stations that survived largely went to AOR. The ones still going have changed further (I don't know that I would call it evolved, but your mileage may vary).
I'll drag out yet another St. Louis example. KSHE was a progressive rock station and has been dining out on that reputation for decades. It essentially became AOR in the early 1980s. Hearing it two weeks ago while in the area for a high-school reunion, it came across to me as more of an active-rock station than anything else.
KSHE used to do an end-of-the-year thing where they would declare an "artist of the year". In 1977 or 1978, I forget which, the artist of the year was....
Fleetwood Mac.
At the time, it made a lot of sense. Fleetwood Mac got a lot of airplay -- whether on KSHE, KADI, or Top-40-ish KSLQ -- and sold a lot of albums.
If KSHE plays Fleetwood Mac these days, it's either on its "Klassics" HD-2 channel or Sunday mornings where it does Music of Your Life for my generation.
Kia's best seller is the Telluride---an upscale SUV. The last one I drove was $54,000 and change:
In the last couple of years, I've had quite a few rental cars that were Kias. (I hate SUVs, so I usually have to go through contortions to get the sedans I want.) In St. Louis, I had a K4. The Kia sedans sit a bit low for my taste, but are very reasonable cars to drive. I'd compare them to Hondas: very competent and comfortable vehicles.
The Kia SUVs have especially striking styling. They're not the punchline for a joke any more.
