They are a must here in Idaho. We put them on our 2000 323 and then the 2006 325. First thing I put on my X5 and I like the look on it and the 3's. If we lived in a different climate I'd think differently but seen too much damage from the winter months of driving.

Do they make them with Yosemite Sam on them? Back off! :rofl:

I agree with JCL (again). Mudflaps look better than no paint. Just don't back into a hard snow drift with the hard plastic mudflaps as I imagine things could get torn up a bit.

Mudflaps
 

I have X5 2009 with Original Sports Pack with 20" Flared Guards and Side running boards. Had the car for about a week and road grim was thrown all over the side of the vehicle. I had rear mudflaps already as they are very standard in Australia. I purchased front ones and fitted myself, best purchase I ever made, still looks great with them on, less cleaning and less stone chips. There is a huge gap with 20" tires that simple stones etc hit the side of the car, even with side running boards. A very worth while a time saving expense. The quality of these mudflaps is fantastic and fit perfectly.

All a matter of personal taste... I have them on my Z4 as well as my X5.

This picture is not mine, but the flaps and color are identical:

My Z4 is six years old with 35K and has no paint chips on the sides or rocker panels, despite being driven primarily on secondary roads.
