Yes, and certainly a seller in that position is going to do his best to ignore it.

As a buyer, I would certainly include it in my personal calculation of what I 
would pay. You're missing out on 20 years of engineering changes, for one thing. 
 For another, it's probably had a lot of idle time for camshaft corrosion to 
get a grip.

OTOH, assuming the price is adjusted appropriately, I'd prefer to buy a plane 
with a runout engine and have it overhauled on my terms.
