Welcome to the Forum, ValerieL!
I agree that the Kawai UST-7 could be a good candidate. At 30 years old, if we believe our rule of thumb that ordinary pianos with ordinary care might have about 50 years of musically useful life, we have some life expectancy left. It is a sturdy model, built to take heavy use, and that it has had a single owner might bode well. Of course, if that single owner was a church, a bar, a nightclub, or a piano teacher, keep looking; they use them up fast. I would be interested in knowing what the seller is asking; it could be an indication.
Alas, that we know so little about you, your present ability, your intentions; even your city of residence. The climate in which an acoustic piano has been kept can make a big difference in its condition over the years. It is possible that there could be people in your area who might be able to help you. The advice to hire an independent piano technician to examine any used piano for condition is really imperative, if you are not able to read its story for yourself. It can save you from an ocean of tears.
Piano Technicians' Guild http://ptg.org
offers a utility on its site that will help to look up its members in your zip code. Not all good tuners belong to such an organization, but reaching out, absolutely cold, for someone you hope is qualified and who can be trusted to act in your best interest, it gives you a little more to go on. Anyway, whatever piano you buy, you will be needing someone to take care of it.
We used to say that inspections run about $100, and an easy one, not at too remote a driving distance, might still be that. Or maybe a bit more Looking at one which is offered in a store, presumably tuned and dusted off, is helpful. If a piano cannot be made to hold a tune, it's not a good candidate. Ask the store if they object to allowing the tech to inspect; it can go either way.
As for the two which are offered for the cost of hauling, the answer is No, and No. If you want to buy a digital piano, get a new one.
I would have assumed you already saw the pianos, and played them, but one of the other responders seems to think it possibly hasn't happened yet. You could write back and give your impressions, or ask any question you may have. We love these piano search stories. https://www.pianobuyer.com/buy-books/
There are several other references available to you, if oyu want them.
Best of luck!
