There are several cars with generous perks (like the Porsche 911 '82). Any time you see any of these auctioned, the perks will probably have been used up (not always but it’s not good odds).
If you want to go on a crusade against this concept you can but you won’t stop it, or even make a dent in it, even if you do it as a full time job… (I hope I’m not giving you ideas…)
I’ve bought several Supras new, used the good perks and then resold them, but only for the minimum (so far they’ve always been bought out, for 138k IIRC).
