either they think your car is a big puddle of water or they really like the scent of whatever soap you're using lol.Just bought a new 2014 Versa Note in sky blue. I've had it for a couple weeks now and keep it clean. I wash the car every weekend. The problem I'm have is that flies like to hang out on the outside of the car. I'll go to the car to find a half dozen or more live flies sitting on the car. It happens with the car parked at different places. I never see flies group on any other cars around it. Do flies just really like the color ? Lol.
