Well, if you look at it, the 69-71 Vettes command more money than the '73 version. Unless your '73 has the 454 in it.
The same thing applies to the '73 Challenger. The 70-71's are worth higher. Blame it on smog.
However the Corvette has had a following for a long time in which history has documented over and over. The Challenger for one, was not as highly regarded at the day, and has just had a rebirth of sorts as of late, helped by the Cuda craze ignited by the
Nash Bridges TV show.
However, the '73 E-bodies are climbing up in price at a rate greater than the '73 Corvettes, I'll tell you that. Because there are just too many Vettes and not enough E-bodies to go around, when demand ramps up some more after the 2008 Challenger is released, there is not going to be much of a supply. Especially when Chip Foose is snapping up Challenger/Cuda projects in the west coast.
So, whats the story behind this '73 you have your sights set on?
