Ahh, Viracocha is displaying excellent JTBD software design. JBTD is Job To Be Done. Google it, it's powerful and so simple.
Yes, auto data providers have highly structured, VIN specific data. Infact, it comes in 'levels' of perfection (or completeness). The more you spend, the more complete is the record.
In your example (2018 vs 2025 F150 XLT), AI can do a OEM YMMT based 'generic' comparison (you'll need AI to be real time) This is helpful in high level research and is seen in SEO landing pages.
Using the JTBD model, the shopper is on the 2025 CrewCab XLT F150 VDP likes what they see and NOW they want a simple way to compare the car they own vs the car they want to buy. This task/solution 'should be' the websites responsibility, but, the JTBD philosophy is alien to these ppl, so, they can't see it.
That being said, this is a perfect JTBD by an intelligent chat bot on the dealer's site. THe bot would need to be aware of the page the shopper is on (Carvana's bot does this) and if the bot has this info, the bot could ask the shopper the YMMT the shopper has. The bot could ask the shopper if they'd give the bot the VIN or Plate#, they'd have the build sheet data for that specific car and it would improve the quality of the comparison (p.s. tradein forms harvest this data and chat bots should have this info if provided).
Viracocha, nice rabbit hole you've found! 
Very helpful for shopper knowledge. Too bad 99.9% of the software ppl in autoare chasing lead gen.
