Looks good except for the wheel wells...you need to keep those spotless, then the car looks new all the time. The X5 has nice smooth fender linings, so it's really easy to clean.

If you've never done it, take off one wheel at a time and use a soft brush with a 50/50 mix of water and Simple Green. Once they're clean, you just reach in once a week with a wet rag and wipe it down. It will make a world of difference on the appearance, especially when the rest of the car is clean.

You can go one step further and clean the inside or your rims (when the wheels are off). That way the rims look showroom new as well.
