not sure if there is a section for this but here I go
Here is my V8 vair at 75 MPH on my way to a show 100 miles north of my home in 90 deg heat
the car ran at 185 and even when stuck for an hour in gridlock stayed at 200 max and interior was tolerable as well in fact not to much hotter than other black interiors vat 90+ deg
I guess my theory on heat control works haha
