Please help I am stuck, and so is my car.

I can’t get my 95 E- 320 to start. Yesterday morning all was fine it started first thing in the morning drop my daughters at school, with no problems came back to the house and park the car in the garage. Around noon time I got ready to go have lunch with my wife I got in the car turn the key on and nothing, zero, just a grinding noise coming from either under the instrument panel or the fuses area. I went ahead and did a search in this forum and I read many threads that describe similar problems which I’m having. I checked the battery took it to a garage, they charged, did a load test, everything pass with flying colors, so I rule out the battery. I then checked every fuse and relays in the fuse panel that I could find and the fuses are all good, not sure about the relays. I then proceeded to check the starter by following the jumper wire procedure that many here in the forum have describe (Dalton, and others) by connecting one end of the wire to the + end of the battery, and by touching the center probe from the connector that attaches to the fire wall behind the brake master cylinder and I got nothing the started did not move, the car did not start. I have to say that I am not sure if I was doing right but as far I can’t tell there is no response from the starter either. I then decide to jump start the car to see if that would get the car to crank but it was the same result, the car did not start. All the lights and all the accessories in the car are working when the key is in the on position, so that rules out the battery I believe. I need help because I do not want to see my car tow to the Mercedes garage I rather find the problem and try to fix it myself. I am stuck, and so is my car.
