Cool car. I built a cobra replica back in 2001, but not one of this caliber.
The body is a kirkham, probably the best replica company out there as far as detail and accuracy. I believe they are the only company that produces aluminum cobra bodies:

Not sure how different this one is, the frame in your pics looks totally custom (amazing, actually).
Using their chassis you can build one for less than $100k.
Seven figures is a LOT!!! Wow!
Pricing from their site:
Our cars start at $56,995 for the 427 models and $61,995 for the 289 models.
Each replica comes standard with most everything needed to complete a car (less engine, exhaust, clutch, transmission, drive shaft, differential and half shafts). For more information on what is included with each car please see the specs for each model.
