In traffic. The problem was that it was two cars behind me, then a truck came and completely obscured it from view. It managed to catch up to me and I only managed this shot of it. You can see the zebra type camoflauge clearly on it. And with the Z4 shot I forgot to activate my lens VR function for a more stable image. :t-banghea Also spotted a few minutes later, BMW PAS again...
I will. I always try to be aware of my surroundings. That technique helps me spot great cars in advanced!
