Hm, not that I am aware of this.
(Apart from the rare competition version #6885, but I think this was a one-off.)

The roadcar has the same large headlight housings, a feature that made the 275 so specific (and IMO old-fashioned in its time).
As if they copied BBR, where the lights look a bit small, too.
The thicker chrome surrounding of the CMR may highlight the effect.

The sideview on the same page looks more correct, but the full frontal view is waaaaay off.

Interesting to see the car anyway, the KK Scale 365s appear like BBR clones, too.
