I went back and forth on the Sport v. Limited package myself, but ended up going with the Sport E package with the Premium Sound. The choice was just based on lifestyle.
I never use the Speed Control on my current car, or the sun roof on my wife's car. Heated leather seats in Georgia aren't a necessity for me. I was also afraid to get leather with a 2 year old and 70 lb dog back there. The other options just seemed like things I wouldn't use. Plus, I don't like the Silver external decorations on the Limited. Do wish I had the fog lights, but I plan on installing them myself.
