Looks like you are leaning toward the Limited because of Push-Button/Keyless Entry and the Spoiler.
Aside from that, you are getting higher quality seats and a more intuitive climate control. Honestly the only reason I preferred the Dual-Auto Climate Control is because it looks better than the manual knobs. It's all preference.
EDIT: Foglights, which come standard on the Limited, are pretty cool too! At least to me
And the headunit--it's not the best but it also does its job very well. For me, I'm rarely playing around with it because I'm always more engaged when driving the car. I don't even listen to the radio because I like the hear the engine working.
Finally, I'm going to PM you some more information! Check your inbox
