Honestly have no idea what the reserve is... Usually range (if you can find one) $30-60,000
But considering this car (from what Im told) is more rare than the supposably "Gone in 60 Seconds" Eleanor:
Which isnt really true because Not one of the 11 Mustangs was a 67 Shelby GT500, most were 289 Mustangs fixed up to look like one.
Its one hella of car that can easily put out 500hp
Dont have any specifics besides the ones posted on Ebay.
Oh Yeah
Q: Did the 1967 GT 500 Shelby Mustangs come with 4 speeds?
A: No, Ford offered an automatic transmission. The GT 500 could be purchased with a Ford C-6 automatic transmission.
