I'm in a similar boat with a 2012 SRT still under 10,000 miles. I bought it in 2019 with about 6500 miles, so I drive it about 800 miles annually. I keep it in as good as condition as I can, and will be garaging it in winters as soon as I can build a pole barn. Here's my opinion on the matter.
Yes, these are extraordinarily awesome cars. I've written at length elsewhere how I think that well maintained low mileage examples will appreciate by maybe a factor of 10x in 3-4 decades. The future is of course unknown but based on cars from the original muscle era's current pricing, and the Challengers being the best of the retros, I think that's a solid bet.
In short, Dodge built around 650,000 total in the 15 year run. Figure most of the V6s will be destroyed from daily driving. A big % of the 5.7s as well. A big % of the 5.7s will be either daily driven or modified and beat on because of their lower price tags. That leaves the 392s and 6.2s. There were less made of these, and probably a larger % will be preserved but that's a smaller number. I'd guess 20% of the 392s and 50% of the 6.2s will be saved from being destroyed from abuse, but that's not a big raw number. In 3 decades I'd guess probably no more than possibly 20 thousand total are in good or better condition, reflecting about a 3% survival rate.
Not driving it is silly. That would be like having an amazing wife, but "saving her" for the next guy. Nonsense.
So, what I will do. I will basically treat it like I would if I had a 1970 Challenger. I'll drive it to keep it maintained, and enjoy it, wash it, take as good care of it as I can. I'll keep it well maintained. Car shows. Parades. Etc. At my 1000 miles per year pace, in 4 decades this will be a car I really enjoyed and still have around 50,000 miles and be considered "low mileage." Even if I double it I'll still be under 100,000 miles. I get a lot of joy from it, despite rarely driving it. It's not the miles, it's the smiles!
What I won't do. I won't make major modifications, won't abuse it, probably won't track or race it or at least not often, won't neglect it, etc. I definitely would NOT daily drive it or use it as a winter driver. I don't use it for errands to the grocery store, home depot, the mall, Walmart, or any mass parking lots where it can be damaged or stolen. Buy a different dedicated vehicle for that purpose. Yes, these are becoming irreplaceable in my view so take good care of the "last of the V8s.... a piece of history."
Assuming the world isn't destroyed, there will be a market in 3 decades, about the time I stop driving. Assuming no damage, crashes, theft, etc. it'll be a nice bonus selling it off having used it for a decades, and the high dollars will be a nice bonus.
