2007 3.0 X5 Sport Package Question

[crvgt]

Was on the BMW USA site building an X5 and have two questions about the sport package.

First, aside from the 19" wheels, what are the exterior visual differences between a car with and without the sport package? The web site says "anthracite headliner" and "shadowline trim". Do these really add a lot to the look of the car in your opinion? I know that sometimes a car in "base" form can look rather drab to me, so I was wondering if the sport package really dresses the cars look up a lot visually. If anyone has a decent picture of what these things are, that would be great.

Second, can the 19" wheels be ordered separately from the sport package? The web site does not seem to offer that option.

Lastly, the rear bumper does not seem to have a cutout for a hitch. I actually own a 2004 X5 and the rear bumper has a cutout for the hitch receiver - does a special bumper need to be ordered?

thanks,
Ron
