I know they made a 79 cobra and cant remember on an 80, make SURE you look it up to make SURE its real and not some nut jobs idea of a cobra aka stuck on cobra badges lol.
As far as value... great question. Not much more than the V8 version I wouldnt think~ what ever price they are asking research and see if you can fine any, which wont be easy to find I dont think. I know my friend owns a 79 cobra and its QUITE rare...
At the 45th anniv show for the Mustang they had 3000+ Mustangs, every kind you can imagine, very rare (and more than one of them) I only saw two 79 cobras.
