When I bought this 2018 ZL1 it was used and looks like the previous owner really babied this car big time. Probably mostly freeway miles and I was able to figure out which city she lived in as well.
The first picture is when I picked up the car with 22k miles back in Feb of 22, and I liked how she used trip A to track avg mpg. It hasn't really dropped too much since I owned it but working on it!
