Windows up when I can, sunroof doesnt work so well but I'm not a fan of my targa or sunroof, but I'll still take it off in the summer just cause.

Otherwise in the Corolla I scrunch myself up so much my knees hit the steering wheel. I like to drive manual real close to the pedals. A/C on low (most my cars A/C dont work to well anyways), windows up, etc.
