They are building thousands and thousands of new Challengers ( I understand they want 100-150K a year).
The law of supply and demand, this will certainly bring attention from people to the old Challenger. Hence people will want a shot at the old one.
Supply down = higher prices. So if you sell your old, expect a higher re-entry price when you have sellers' remorse.
Take the new Mustang...a very cool design. Remember when you saw one for the first time?
Can you say the same today?
So eventaully we'll see many V-6 and base V-8 Challengers so the design will dilute and blend in the public's view.
First year will be hype, after that it'll settle down and the serious modding begins!
