Salina, KS to Park City, UT. I thought that was good mileage considering it was a mountainous winter run on oversized (205 vs. 195) Michelin Xi3 and at fairly high speed with a loaded car. Two people with ski gear filling the back seat. In town mileage was a low 38.5 BUT it was very cold a lot of time, 10 degrees, so short runs with the heat on and lots of remote start sessions to warm up the car.
