I like the look with it on... besides you never know when you might use it... I've used it a few times this winter not planning to, so I'm glad it's there, and I keep straps in the rear storage area just in case I need to strap a mouthy passenger up there :thatfunny . or extra cargo.
I ditched the factory racks for thule utility bars for my snowboard carrier. during the summer months i just take the whole thing off, mostly because i don't want to leave the carrier on and its eaiser just to remove the bars themselves. i don't really care about the way it looks to be honest. i'm too lazy to care.
I think it depends on the look you are going for if you're gonna lift it and put a grill gaurd on it with "muddn" tires id keep it on. But on the other hand if you're going to lower it and ride spinners or big rims id take it off.
I saw a white D with the cargo bars painted white... but the rails the bars mount to were still black. It looked really dumb if you ask me... especially since it looked like they used flat or satin spray paint on it... too bad I did not have my camera... :WHT:
