hence needing to know how to identify options without a build sheet.
OK, the main visual clues to the S model are:
- S badge on the bootlid
- S designation at the bottom of the speedo
- The AMG emblem is embossed on the front seat headrests
- Contrast stitching on the seats and centre armrest and silver seatbelts
- Illuminated front door sills
- Red brake calipers
- S chrome tailpipes
- Electric roller blind on the rear window
I've seen a standard car advertised as an S model by a dealer in Essex. It had been dollied up with the S badge on the bootlid and illuminated door sills but lacked the other features, so check carefully if you're looking at what purports to be an S model car.
As far as options go, there's no easy visual clue to an LSD being fitted on a standard car, so assume it hasn't got one as it was an unusual option to specify.
A reversing camera is easy to spot mounted behind the chrome bootlid trim above the numberplate.
Multi-Contour or Dynamic Multi-Contour seats are easily identified as they both have a set of controls on the side of the seat adjacent to the transmission tunnel as can be seen in this photo:
If they're the dynamic version they have the "Dyn" button (the one with the two red LED's in the photo) and tab controls for the adjustment; the non-dynamic version has thumb-wheel adjusters and no "Dyn" button.
Ventilated seats have two air intake grills in their back, towards the top of the knee cut-outs, and extra control buttons on the centre console, outboard of the heated seat buttons, and with blue LED's in them.
It's unusual to find a car with only part of the driver aids such as Blind Spot Assist, instead they tend to have either the full Driving Assistance Package or none of it. The easiest tell-tale is that a car fitted with the Driving Assistance Package has the main star on the grill closed like in this photo:
On cars without it, the segments between the legs of the star are open mesh like the rest of the grill.
Split / folding rear seats were an option and are self evident.
Keyless Go should be obvious, but if it doesn't have the Start button in the ignition switch, powered boot lid closing is a giveaway.
The Night Package gives you gloss black exterior mirror housings, front apron trim strip and front splitter, rear apron trim strip and tailpipe trims, side sill panel inserts and window surrounds.
Other than that, there are various (expensive) Carbon Fibre option packages and Designo options including a Dinamica roof lining.
Hope that lot helps?
