There's a low angle shot of a wide wheeled, bolt on arched 240Z on the previous page. The watermark lead to a flickr account that contains these, some new pics of famous cars and a couple of pics I've seen before, but with the watermark cropped off.
What's the gold bracket sticking out of the bonnet on the BMW?
Tow hook presumably, I suppose it must be bolted to the strut top, perhaps triangulated to the rest of the shell. Maybe it's the best place for it on that particular car, or maybe it's just to make as go "woh look at that epic '02, wtf it's got the tow hook through the bonnet!"
The Riverside Fb page had a couple more pics this morning.
Hnnng! Gold detailed deep streets are all kinds of amazing.
