Also, regarding the seats.
The 93+ ones look nicer and more modern.
They look more like leather than the older generation too, and its difficult to tell they are vinyl.
As usual for Mercedes, they are harder than the average leather seat. The result is less fatigue on longer drives.
The older seats are just as hard, and provide the same support, but also have those soft baguette shaped pleats which make short rides and long rides both ultra comfy.
