Higer vs Lower Mileage 328's

I looking for opinions on the higher vs low mileage cars. I don’t want to rehash the mechanical issues of a low mileage garage queen that has issues due to lack of use vs a high mileage driver that has issues from too much use. If there are two cars in similar mechanical and cosmetic condition one with 25k miles and one with 50k miles obviously the low mile car will sell at a premium. If I owned both cars for 5 years and put 15k miles on them, when I sell, the now 65k mile car will sell for less than the 40k mile car. Will the relative discount remain the same or is there a point where the only way to sell the high mile car is with a very deep discount? On the TR forum a comment was made that you can buy as many under 25k mile TR’s as you want and that implies that there may be no buyers for a 50k mile car. Am I missing something in my analysis?
