We get your point about the things you find later. However the real key is to do a thorough PDI before you leave the lot.
Consider everything you find later partially your fault for not finding it before you sealed the deal.
If you take this approach you will slow down and take all the time you need to scrutinize everything. Let the dealer know you plan to take lots of time looking the unit over.
Scrutinizing everything sounds like a big hassle but in the long run it will save you headaches and time down the road
