Mystic. Hands down
I'm pretty sure that all the colors except for MC are not cobra specific. so the rarety issue is a non issue. It seems every time I see a co, zy, ow or sy seems to be a crapy v6 that has'nt been washed since the day it was sold new.
Oh can't forget RF, there must be a trillion V6's running around
Competition Orange, hands down, absolute coolest and most rare color on a Cobra!!!
it's definitely the rarest.
actually satin silver is the rarest
they only made 323 of them (242 coupes/81verts), as opposed to 353 comp orange cars (281 coupes/72 verts)
