I was parked next to an 11MY XS, square fogs and chrome tailgate etc but noticed it did not have coloured mirror caps or painted door bottoms etc. My 11MY GS SD registered in Dec 2010 has the coloured mirrors etc.
Is it only SD that has update? SD I thought was purely related to 190ps engine. All FL2's (3) Gone
2011 Mercedes C180 CGI Gone
FL2 GS Auto SD with heated leather, factory tints, alloy spare and a few other bits.

SD has something called a style pack, basically body coloured headlight washers, mirror caps, lower door and bumper trims in body colour.

Probably a 150 bhp TD4 which tends to have black door mirrors and lower body parts.

In hindsight the extra £1000 for an SD4 over the equivalent TD4 was probably a good deal that I would have gone for if I had opted for the auto, with a few extras for the money in addition to the extra 40bhp:

Rear Bumper - Premium body colour
Two bar Titan finish grille
Door Handles - Oberon
Exterior mirrors - Premium body coloured
Headlamp powerwash jets - Premium body coloured
Sill covers - Premium body colour

Maybe next time!

It's a fair bit more than a thousand pounds for an sd over a td at least double that

Maybe when comparing a Man TD4 to the SD4, which is auto only but an SD4 auto list price is exactly £1000 more than a TD4 auto - a price I couldn't stretch to.
