im discusted with old guy purists

Ok,the other day,an older gent brought a ezgo golf cart for my bro in law to paint.I happen to be there working on my 71 dart,when the guy asked my bro in law,who ruined the darts in your yard here?MY bro in law said,they belong to my bro in law,and hes right there working on it now.Well the guy turned red,because he new i heard him,hell,i was standing less than 5 feet from him.I simply asked the man,sir,why do you think i have ruined my cars?He tells me that if there not 100%original,then they have no value.So i told the guy one of my cars was a 6 cylinder,the other i bought had a lot missing,and wasnt a 340 car,so i dont feel like im destroying a piece of history or any thing.I know there are people that dont like what i do to my cars,especially older folks,thats ok,i dont like how they pretend to restore a car original and then use basecoat clear coat paint on it.That is about as original as my 73 six cylinder dart,that now has 17 inch cobra wheels on it.But i dont tell people there ORIGINAL cars are crappy,were crappy from the factory,and are still crappy because there put back original.I told the guy,if he wanted to waste his money putting the original slant six back in his 69 charger,thats his choice,ill wave as i pass him in my modified 318 dart,that people actually like to see.
