The interior looks lovely and original, do post more detailed pics.
Please take these observations positively, I am an old fan of your work:
Front bumper looks quite nice but square fog lights would match the shape of the headlights.
The rear bumper needs a bit of alignment and exhaust needs to be a bit more like the original one from the W201 Evo.
A ducktail spoiker on the bootlid would look killer.
The AMG logo is a modern one, not the one from the time of the 201, you can find the correct style easily.
Try to find some AMG style wheels.
Steering wheel isn't looking too good, needs to be something with some more black in there. Try to find an AMG or Silberpfeil style steering wheel.
Consider replacing the gear knob with a black one or paint this one black.
