I'm of the opinion that the 1980's were responsible for ruining more Muscle Cars than the 1970's. So many over-restored / incorrectly "restored" cars from that era -- braided hoses, Pro Street, and, worse yet, original items/parts which were thrown away or plated-over, forever ruining their originality.
I, too, enjoyed D.O.H. as a youth. I can't stand it these days -- really, since the mid-1980's as a teen. A friend-of-a-friend had (he sold it some 15 years ago) a 95% original 1969 Charger R/T 440 in factory Hemi Orange. He had to hide his car because of the clowns who were on him to sell it to that T.V. show.
He knew how the cars were "treated", and told them to pound sand.
And, this was during a (awful) period when a 10 year old car - in the stranglehold of the 1979-1980 OPEC crisis - wasn't worth the ground it sat upon.
