The 2 dailys are parked outside on my driveway (CX-3 and SX4). It seems birds have either taken a liking to the colour of the CX-3 or they hate it since almost everyday I would find bird poodoo on it. The SX4 on the other hand (black colour) hardly ever gets targeted. The GF and I try our best to get it off ASAP once we notice it being on the car (it's also heavily waxed up so the paint is protected and the car is wrapped in the usual spots should the dung end up landing in those areas).
I think we picked the wrong colour CX-3 by choosing CM, my old Sentra SE (red) also flys under the radar most times from the projectiles our winged friends like to deposit on the land of our dear earth.
LOL. I have the same 2 vehicles. SX4 is white, though. It seems to be more of a target. Best thing about the ceramic CX3 is my coworkers have been arguing over what color it is. Depending on the lighting, I've gotten white, grey, silver, and blue-grey.
