Money put into Coupes
Sounds like a lot--but keep in mind the first year--a 1970 model Coupe available in North America had a delivered price of $10,000 USD. That was a lot of $'s in those days and by the end of NA model availability in late 1974 well equipped E-9's were around $16,500. I was here to experience all of the preceeding evolution. In 1968 when I moved to SoCal I purchased a 4 BR 2 1/2 bath single story ranch home with 3 car detached garage and a great ocean view on a quiet cul de sac in a very desirable community--Corona Del Mar, CA for $46,500. Same home today is around $850-900,000 largely due inflation or devaluation of our $'s purchasing power.
During the disastrous days of the Carter administration the USD declined very rapidly in value in the face of the Duetchmark (sp?)---not unlike the steady devaluation of our currency in the past 40 years since there is no longer gold or silver backing our currency, just paper being printed by the Federal Reserve. And--once upon a time $50K per year allowed living the good life--perhaps still in small town USA but not so today in a large metropolitan area.
Perhaps the foregoing class in reality economics can help keep the steady devaluation of the purchasing power of our USD and related commentary in proper perspective As an example--a very good Coupe at $40,000 of todays cheap USD's is equivalent to $8-10,000 in purchasing power of the then USD when these cars were new 40 years ago.
