I was looking at an SX. Then there is the SX Prestige, X-line, or X-pro. I then see that if I want a bench seat in the second row, I need to stick with an EX. What do all the different trim packages give me. I know leather seating starts with the EX and that the X-line and X-pro add the blacked out wheels and trim. What else am I missing with the EX, the SX and the SX Prestige?
