I got a new job which requires me to drive about 70 miles round trip from the house. My '06 Silverado is doing fine but drinking a lot of gas and I'd like to avoid further wear and tear. I'm looking at a used (2014 or newer) mid size sedan to be my commuter vehicle. I'd like to stay under $15,000 if possible. Do you guys or gals have any suggestions or experience with any of these? I've only owned trucks or SUV's so my experience is limited.
