I just cringe when I see the word "investment" when used on most modern cars. Some very limited production cars such as the new ZR1 Vette, Ferrari's and such might fare OK, but the new Challenger is just made in numbers too large to qualify for investment grade. . Twenty years from now, $40K invested in a 70 Challenger will have done better than a current one. The original ones are doing well because us Boomers had one back in the day. They were more affordable to the young than an SRT is now. There was a huge cult following of drag racers and Trans Am racing that kept everyone bench racing the cars, and you could buy on Monday what you saw racing on Monday. That's the stuff that creates legends. Because of that, the demand just won't be as large.

Secondly, there's a sizable replacement parts industry available which make restoration easy. The current generation of cars will require an EE degree to keep running.

The only thing that I can see that would help the current cars is a combination of Chrysler folding and gas prices getting so high that following cars do not eclipse it in performance. Relative to other new generationChallengers, the SRT's will be worth more though.

Just my opinion.
