Indeed
@Markos, the "complete restoration" term also makes me wonder.
One could still spend 10k (easily) on rust remediation of the front fenders and strut support area, and no-one would call it a waste or unwise.
Surely the Werkshop would have advised to do it, given the deep brown pockets of rust that we get a glimpse off in this pic:

Only the top layer was addressed however. Probably by choice by the customer. It is as it is.
But then the Werkshop still sticks the placard on there? To me this is misleading; this is NOT called a full resto in my part of the world.
Would they say "All is done, nothing left to fix" if they looked at the car again?
To be precise, my rant is aimed at the Werkshop, not the owner who paid for it.
The money spend on the Baikal paint job (wild guess, 10k paint vs 10k on rust remediation behind the fenders?) to me is a bigger dilemma; rust from within will grab a hold of the paint from behind, limiting the lifespan of the paintjob to, what 10 years? 15 max?
That's a 1 to 2 K of value lost a year. Which wouldn't be the case if the rust was properly taken care off.
Still, not my car, and not my call.
And an honest reprentation of the car with all those resto pictures, so this makes the seller all the more the 'gentleman' to me.
Now if all car sales men would be honest like this gentleman, the world would be a better place
