Why do these "models" cost so much?

To be honest it would depend on how historically accurate the Kirkham or Kirkham / Shelby, I'm talking about the alloy cars only, is put together. I feel that if you are driving a Cobra, be it a 289 or 427, the only way to get the originals driving experience is that the car must have all the same build features that were used in the original cars construction. This would include everything from the chassis and body construction to the complete drivetrain and all the nuts, bolts, switches and every other component that made a Cobra a Cobra. If the "Cobra" that you are looking at does not meet this criteria than you are looking at someone's version of a hot rod, there's nothing wrong with that as it may or may not out perform a "Cobra" or it may be better engineered than an original Cobra but the driving experience is definitely not like driving an original Cobra. As for the Shelby vs Kirkham, Kirkham supplies SAI but has a far better customer relationship, Shelby provides a CSX number. I apologize in advance if this offends anyone but it is what it is.
