I usually don't see e92 m3s on my drives, but the weekend I pick mine up I saw two. One of them was a white E92 M3 with a PowerHouse Amuse Ericsson Carbon Fiber boot lid (I believe), exhaust, carbon roof, and DCT. I think he saw me, too and I heard is DCT downshifting.
This was around the 134 W 101 South area on Saturday, OCt 27th.
The other was a stock, white, e93 m3 at Glendale off of Broadway yesterday.
I was the stock AW E92 M3 with carbon roof and black powder coated exhaust tips.
