mercedes custom body kit with vertical doors...
 

saw this last night on oxford street. looked new and was silver.

the saloon back was steeply sloped like fiat coupe and with similar round lights

the nose was also sharply steep too, like the box shaped alpha that came out.

on the side, it said something like vertical doors in chromed lettering.

looked very smart, but a bit odd, especially for a merc - had all it's merc badges too.

any ideas what it is?

next time i'll make use of my camera phone as it was parked, der!
