I’m assuming US?
One thing to note is that the US started requiring back up cameras in all cars manufactured after May 1, 2018. Your best bet to find a dumb car would be to look at base trims of some cheap 2015, 2016, and 2017 cars. Cars like the Elantra, Forte, Sonata, Altima, Versa, and Sentra did not have touchscreen displays in their base trim. I know because I basically lived in rental cars during those years and am very familiar with all of them.
Now, definitely watch out on the Korean ones though due their cheapening out of security equipment…but the Kia Boyz have probably salvaged titled all of them by now. I would also be hesitant on buying a used car with a CVT because it’s a crapshoot if the previous owners actually kept up with the mandatory maintenance on them.
I think the Mazda 3 or Toyota iA are good used car choices to keep on your radar. There is a “screen” in both cars, but they are dialed controlled when the car is in motion. They both have a REAL automatic transmission too. No CVT stuff to worry about.
