Not useless. Just ill-defined and with only a very loose association with "airworthiness" which is already defined by an Annual. An Annual cares not what the condition of the plane will be the day after it rolls out -- just that it meets standard on the day of sign-off. A prebuy should be concerned with a plane's history, comparison with seller representations, and likely pain of ownership for the new buyer over the next 5-10 years.
I follow a well-defined type club prebuy checklist, but honestly, if I don't find anywhere else on the airframe with signs of corrosion, there are plenty of spots on the spar that I'd not go looking at -- either due to poor accessibility or a general "no smoke, no fire" point of view and trying to limit a 6-8 hour inspection to the big or likely pain points and items discovered that merit additional looks. Running the full annual checklist on the planes I look at is typically 40-50 hours.
This shop's prebuy fell down on the "pain of ownership" point for certain, or sees it differently than I do. I don't know Mooneys but I'd suspect a grotty spar means corrosion elsewhere on the airframe that the prebuy also missed, and if this is a common thing, they should have popped a panel or two and looked. While I think the shop is getting slagged a lot in this thread, it does seem like their prebuy was light and their annual was heavy, and that's not very nice to do to a new owner.
Savvy was created to prebuy the prebuyers and try to bring some uniformity to these things
