Really? I don't think that's quite the image Walkinshaw and their admen had in mind when it spent millions to convince people that these magical mods are worth many thousands and add thousands to resale (coz remember... Tom)!
Way I see it there are people who buy sporty cars and never explore the potential, whether that is longevity mods, fuel consumption mods, cooling mods, handling mods, wheels and braking mods, NVH mods, exhaust note, induction roar, never mind actual performance mods. Basically they don't care, and that ultimately shows in terms of mechanical sympathy. It's not that they don't want to, is because they are risk averse and lack the required competency. That's the thrill in discovering treasure in a well-sorted car owned by someone who gives a ****.
I see two types of car buyers - those who want a plain cheap AF veal parmy (offal schnitzel in disguise) and those who appreciate the important difference with proper veal Milanese or saltimbocca a'la Romana. To the former pub-goer it doesn't matter plain cheap straight parmy known commodity (unknown origin) on special, to the latter its an almost spiritual ascension of appreciation for the thought and effort that results in the detail. Pub parmy and a glass of factory beer (coz all same shiit product thrown together) vs the proof of satisfaction in enjoying a scallopini - the way it comes together with a glass of dry red, without need for explanation it just works, with so much more value passed on.
Vis-a-vis car mods, is not the sum of its parts but how it comes together, else buyers are shopping for price based on commodity.
A mate in the wine trade sells wine bottle openers for a living, not like 50¢-$5 stuff, but $500 to $1500 for bespoke custom gear. Point being that maintaining plain vanilla factory, known item, boring as batshit shoeboxed item in tissue, on the basis of offloading it in pristine condition to suit commodity buyers is, I suggest, not the way to enjoy the potential of what you have, the possibilities of what could've been be with a little dedicated thought and courage, and the satisfaction of passing on the story (and value) of what's been created to another like-minded buyer.
