Don't worry about the comments here my friend. LOL...lots of 'grumpy old men' (me too...and proud of it) with attitudes and opinions on EVERYTHING
I have lived in Texas for 27 years now, and completely understand your heat issues, but AC may be a little impractical that's all. I actually added 'fans' and vents in both sides of the dash, but they only blow air at ambient temps. It helps, but with a roadster, real AC will just be wasted.
Now, with regards to your comment about the little woman..."
without hearing her ***** the entire way about the heat"...most Cobra enthusiasts would recommend...
1) change girlfriends
or
2) leave her behind
Good luck out there. Since you live close to LSC in Ft Worth, go visit them. (Even though I have one, not necessarily saying GO WITH LSC, although I DID!, but with a 1 hour visit, you will KNOW if a Cobra is what you REALLY want and then you can take a little time to choose which one) Take a look around, sit in a couple of Cobras, ask for them to take you for a 'spin', talk to Brian etc.
Good luck
