We have had days almost to 90 degrees here in the Tampa Bay area and I have not noticed any extra heat loading inside our Mach E due to the glass roof. It was one of my concerns as well, but it hasn't been an issue for us.
Hello sorry I posted in the registry section first, long time stalker, now second time poster. Glad to be here. This forum has taught me so much of how to do what with our newest family member...Big AL. We found him sitting by himself and brought him home. Looking forward to swapping knowledge...
