Who cares!??

I'm not sure how to say this or if anyone else feels like I do, but is it right to violate a classic config? I mean how many factory dream mopars have we all seen violated by neglect, a stupid change by the owner, or just plain replacing w/non chrysler, aftermarket junk' where the 'magic' of that special factory config is lost 4-ever? I mean I'm serious when I say it should be illegal to violate historic pieces. It is actually, but not in the classic care market. These old mopars ARE just that... classic historic pieces, a lot of them trading for more than famous works of art! But the difference is that the law isn't gonna make anyone respect 'thier' historic value... it's completely up to us! The good thing is that most classic mopar owners are owners out of love of the vehicle. It's the rich, 'money is no option' investment collectors that hoard all the best of the best in warehouses to auction later for profit only that piss me off! I'm not one of the rich mopar collectors, so I'll never be able to enjoy sitting behind the wheel of those beautifull beasts... mainly because their value has been so over-inflated by these people that the true lovers of these cars who put their heart and soul into resto-ing their A-bodies with pride, are robbed of the availability/affordability of the cream of the crop by the rich investor-collector types.
I know it sounds like sour grapes, and it is to a point.
And I know my '72 Demon 340, missing it's orig. trans. & eng. dont make a ripple in the lake of all those over-valued other mopars, but it's just as awesome to me and as my part in the mopar comunity, I just wanna do the best by it... that means not screwing it up by violating the factory config. unless having it's orig. eng/tranny missing already shuts the door on it's collectability??
One day when I'm gone, my Demon's still gonna be here and what I leave to the world, I want to be the best representation of classic mopar muscle. Don't ask me why I care so much about 'em... I just do.
With that said, do I change the interior/exterior colors to what I think would look cooler, or is it still at a point where it 'should' be restored to OG?
