I don't see your question?
I was looking for market value
I like to use Nada, KBB doesn't go back as far.
Here is the start page for the 1971 Ford Mustang Mach 1 2 Door Fastback , http://www.nadaguides.com/Classic-Cars/1971/Ford/Mustang-Mach-1/2-Door-Fastback
I used the 80201 zip code.
Here are the results.
If you have a 4 speed, ac, ram air or bucket seats it is worth more.
thanks for the response. How can I send some photos?
