Man, there are cobras for sale all over the place. Check out
427 Cobra Country--Ford AC Cobra replica manufacturers SUPER-SITE.
There are TWO CSX Shelby glass cars ASKING $105,000. You can buy a brand new Shelby Roller (w/out trans and motor) for something around $65k I believe. There is NO Superformance worth $100,000, unless it has $45,000 in cash in the glove compartment!!
Kirkham is THE best engineered and best built cobra on the market, flawless aluminum body (he sells bodies to Shelby). The Kirkham cars are also listed in the Cobra Registry - due to being - basically - a genuine continuation of the originals - just much better all around quality than the originals.
If you want a cobra there are several Superformance cobras on Cobra Country from $43,000- $60,000. There are ERA's available (in my opinion a better fibreglass car than Superformance) in the high $40,s - to $60. Shop around ... it would be a huge waste of $$$$$$$ to buy the Superformance you are looking at. No one familiar with cobras will EVER pay that for a car. Keith Craft has done several Superformance cars with his 427 (stroked 351) for the mid $50's.
Go visit Kirkham. If the Shelby name is important - buy a fibreglass CSX car and have Keith Craft put in the motor and transmission.
