A little bit of both :)
Just drove my Huracan 1400 + miles from NYC to Hilton Head, South Carolina with over 100 other cars...in 100"+ weather, rain and crazy weather that felt like I was in a Hurricane. The car gave me no issues whatsoever and now I'm back driving it in 100"+ Las Vegas weather. I wouldn't worry about the heat and running the AC! Enjoy the car!
