I don't recall feeling any excess heat on our trip to Wisconsin this past summer, but then again I had Sonya, Mahalia, Dakota, and a bouncing rear cargo carrier to distract me.

I can tell you that our '04 Axiom is TERRIBLE about heating up on a long drive... but the heat is on the passenger side of the center console, perfectly located to scorch your passenger's feet. It's not heat blowing from the lower vents; it's heat radiating from under the carpet. I'm glad I don't have that level of issue with the VX, but I sure would love to move our Axiom's tranny dipstick to my engine bay.
