And the 73-74s are a great investment if you plan on holding on the the car for a few years, and also plan on restoring back to original.
I figure that as the 70-71s go into the stratosphere pricewise, the rest will follow along...not as crazy, but figure if 71 Cuda starts costing 70 or 80K, as some do already, where will that take the later models? Only up! Of course the later models SUCK...
