Are there any cars that DON'T have a way to adjust the brightness of the dash lighting?
Every car I've ever owned (86 Chrysler, 2000 Suzuki, 2016 Subaru, 2019 Tesla) had a dial to adjust the brightness of the dashboard lighting, or in the case of the Tesla, adjust the brightness of the screen.
Sure, I couldn't completely shut anything off like your Saab, but I could easily turn the brightness down pretty dim.
