I have lots of friends that are in love with the 70-80's American cars, and while I appreciate them I find the 70's and 80's cars IMHO, are not as desirable unless you really are an American Muscle guy. They are simply more raw and have a lot of plastic.
I liked that quote on the Ferrari race driver where he called a spade a spade... that made me chuckle, yet I look at the Carlisle show, some old cars are just that, OLD....
IF you decide to get one, a full restore will be the same price point as any car when you do a full restore. Especially, for the man hours to do it not counting the parts needed.
I personally find that you need to really like the car before you jump in as if it has 60hp your still going to be going 60hp fast.
As to an electric IM I have no desire for one and the price point has enough margin to start an elite exclusive club.
