Hello Andy

and give your correct FIN (the FIN you have postet is to short) into the white box, so you have alle the options that the owner of the car has ordered. So there also is a code with a 9xx number whitch must be the AMG-paket.
But I´m sure that your car is an orginal of the 200 series.
By the way, you don´t have an Getrag gearbox, only the 16 valve models had this gearbox.
The AMG-models has an gearbox from the E300-24V whitch has also the first gear left-down. This gearbox has been strengthened by AMG.
At this site

you can also find more informations to the AMG-models (and all othe 190 models also)
