I went with the regular Sport line instead of the Xline. The main reason was for the sport seats. I really liked the look of the Xline more with the dark wood trim and the wheels. But in the end I decided it was the sport seats that was the winning factor.
Also the Ultimate package was a no brainer for me for an extra $185 since I absolutely wanted the Premium and Tech packages. I'm not sure how much I would use the rear camera but I figure it would help resale value at the very least.
