While I appreciate the "purist" attitude of the bare bones roadster local climates can be detrimental to getting out and driving our cars. I've seen references to AC in some of the posts from our brethren in Arizona and Florida just off the top of my head. Those areas can be really uncomfortable during the summer. Big question is do you want to drive your car or sit in it in the garage making vroom, vroom noises.
I really enjoy driving my Cobra and go to some lengths to do so. In my neck of the woods the driving season is about 3 months. I can extend that by another month with my heater, top and side curtains. Going for a 3 or 4 hour drive when it's 40 degrees outside wouldn't be possible without them. The additional driving time is worth more to me than the flames for having them. If I were in the hotter climates AC would definitely be on the table.
I'll pile on with tongue in cheek shots at one of our club members who owns a GT40 but everyone envies him when we're punching through an unexpected downpour.
