I had a SAAB 9000. The optimal temperature was 69°F, but the thermostats was calibrated in Centigrade, so you go 20° or 21°C. It was a butch. My Lexus Hybrid had a certain temp … I can’t remember it now.
My [current] 2018 Audi Q7 seems to like 75, though after awhile, 72 is more appropriate and, if I’m wearing a heavier coat, 69°F.
Ladies and gentlemen, car thermostats were never meant to be absolute. [For my fellow physicians, it’s like monitoring CVP: Changes are significant, but absolutes are not.]
I’m looking towards an Air Grand Touring in burgundy and tan interior. I had a Camry that was burgundy and grey, and it doesn’t work after awhile. Plus they have to prove their superiority to T***a. I’ll give them two to three years. Not willing to put a deposit down yet, but in a year or two. I don’t want to be stuck with a DeLorean or, lord help us, an Edsel.
