Cars, and anything else inanimate will only chill to the OAT and no lower. With that in mind, if the wind is blowing, they will get to OAT faster, but will not go lower than the ambient temperature.
The effect on your water pipes is because the wind pushes the boundry layer of air away, or goes through the insulation quicker. Any wind will cool things off quicker, but no more than the temp of the air.

I think it's semantics- I understand about the "invented" wind chill term, but I don't buy that it doesn't affect inanimate objects. Wind on exposed water pipes, on a 25F ambient temp day/night will definitely supercool and cause to them freeze when they wouldn't normally freeze on a calm 25F day/night. By the same token, a car parked in a unheated garage at sub-freezing temps will start easier and be less prone to fuel gelling in the lines than the same car parked ouside in windy sub-freezing temps. Air movement pulls more heat out of the object.
I don't know if anyone commenting on this subject is basing their info on experiments or studies- I'm not. Just my observations based on personal experience. BTW- Wikipedia information is not necessarily fact- it's open-source, therefore subject to misinformation.
