I have a neighbor that drives a VW
I believe it is this car ( passat ? ) :
I tried to get a good shot of the underside of the car, but i also didn't want to risk getting shot at so I set my phone on video and acted like I had dropped something on the ground while holding the phone down low.
What surprised me was that the entire underbelly is covered and has dimples in the paneling, much like the Audi i mentioned earlier.
Unfortunately, I'm on a Mac and i cant bring in the video. I will post some actual photos as the opportunity presents itself.
