My '96 4Runner had a brush guard on it and it looked good. My '02 Trailblazer had a brush guard on it and it also looked good. Both of the front ends on those cars were nice, but the brush guard completed the look to them.
The front end of the WK2's look too good to cover up and looks very complete without it. But that is just how I feel about it. She's your baby, you make her YOURS and share your pictures of the finished product. It may help someone else make the same decision.
