I don't think this is a Sport. How do you tell?
My X5 doesn't have a sunroof (I had an MX-5 for 12 years and a hole in the tin roof doesn't exactly light my fire), nor a CD stacker, but gets Sat Nav and TV for some reason.

Judging by the wear on the spare (10 spoke 17") the car must of come with 17s. I suspect it only had 20s fitted for the car yard period. I also drove it on 19s with the wider rears, but they wanted extra $$$ so I suggested they could keep them and give me a set of OE 17s.

I thought 18s was the ideal compromise until I really started to throw the X5 around to explore the limits. An old motor racing habit of mine where you find the limits of adhesion and then you know what the car feels like if you ever need to use everything at your disposal to avoid a big bang. My car is currently wearing Toyo Proxes on 235/65/17s which have shown a remarkable level of grip for a 2 tonne Tessie. The roll centres (suspension) on this car are really well set and makes the car feel much closer to the ground when cornering than I would have expected.

The tyre noise on smooth tarmac is a bit much for a road tyre though.
