The interior actually stays pretty cool. I parked in a no shade lot on the Houston Texans game this last weekend. Not a cloud in the sky and temps in the 90s. I'm not going to say that the car felt air-conditioned when we hopped in, but the seats were not the frying pans we expected and the cabin cooled quickly. We have nothing but the solar tint currently (not visable, but UV blocking) and I accidentally left the moonroof cover back, so we were expecting an oven. Finally a pleasant suprise.
