I saw this on my way home from work. Its a new M3 thats not out yet. But it blended in with traffic nicely. It had a carbon hood and some side panels that were covered with black tape. I only realized it was a test car because I knew the car hasnt been released yet. I only got one shot cuz I was in traffic. This is yet another reason living in LA is good. You see test cars all the time
