Hi all.
I'm trying to figure out which BMW model I saw on the road.

I was sitting behind it in traffic, and really only saw the rear of the car. It was de-badged save for the BMW logo, so couldn't really tell...

See if you can suggest what this was:

- I think it was a 2-door coupe -- the rear looked squat, like coupe styling
- Rear was 'square', and had two tiers, trunk lid and fender. The fender stuck out further on both sides. It gave a 'blocky' impression but looked very nice, very cool. BMW badge was on the trunk, center.
- Top-to-bottom, the rear was very compact looking. It almost resembled a Mercedes SLS.

It was definitely super-premium, like an SLS... these are the closest two BMWs I can find that look like it, but I don't think either one is what I saw:

M6 Gran Coupe: http://www.autoguide.com/auto-news/w...oupe-back1.jpg
Pininfarina Gran Lusso: https://lh5.googleusercontent.com/-B...o-Coupe-25.jpg

The thing is that I swear the fender extended further out to the left and right than either of the cars above do, and the curves/angles coming down into it from the trunk were more 'square' (still rounded, but looked square--and distinct). Maybe that was just my perspective...?

Hollywood Blvd, so go figure. It had a custom auto shop / racing logo on the window, which sadly I can't remember.

Can anyone suggest anything that matches this description???????
