Cadillac six poor gas mileage.
Before the six I drove a Ford Focus, 2014 model. The features I miss the most are Bluetooth capabilities, and the improved gas mileage. I currently spend $40 on gas per week, vs the Focus where I maybe spent $30, and I might not have to fill up until half way through the next week. The six is good for someone who wants a lot of features but if you have a long commute like I do (2+) hours per day, assuming I do not have any errands to do, it drinks gas very quickly.
