I have UV tint on my car, not just the fancy tint and most of the time i have my car parked out doors with no shades. It can get really hot here in Hong Kong, sometime when i get on the car, it says 40+. Even after 10-15 mins on full blast, still not as cold as my good old e36, forget about comparing to my w210 which is like a freezer.
I did measured the temp off from the vent when I had the car indoor and it surely did read 5 degrees, but not outdoor.
