I have a 2006 Titanium Metallic 4Runner and am wanting to get a brush guard or a bull guard but do not know which color or which style. I don't know what would look best on silver; the black, the stainless, or the combination brush guard. I also want to get the tail light covers as well. If anyone has any pictures or advice they would like to share I would greatly appreciate it. Also, is gas mileage or driving affected by adding a guard?? Thanks so much.
