The last few weeks have been rather slow progress, but it was tedious work, which took forever. I'm currently getting all the parts ready to get them painted. Since W203 like to rust, i had some de rusting to do. The 4 doors took over a month, till i had cleaned everything up. I opened up the bottom on them and cleaned out the rust as well as i could and then used the chassis glue, which i previously used on my wheel arches. The hood is also pretty much ready for the paint process, after removing the ornament socket. What is left now, is the trunk. I've dismantled it and removed the spoiler, but have to clean it up some more. The chassis now has a layer of primer and two layers of filler. The next step would be the base coat (hype). Another thing i ticked off, are the brake lines. The rear ones had some slight corrosion, so i decided to make all brake lines new from scratch.

Need an update. I saw pics on IG and there was color! Looks great too!
Are you a Collision Repair Technician?
I did my apprenticeship as a car technicianwith focus on electrics and high voltage at a Mercedes dealership in 2013 and after finishing the apprenticeship in 2017, I worked at the dealership as a tech doing mostly diagnosis on electrical systems. I switched to an franchise Mercedes partner in 2022, where I work now and work in their body shop. In a team of about 15 people, I'm the one who does all the electrical and mechanical repairs on the accident damages. So everything from calibrating assistance systems, diagnosis, HV work to replacing axles, subframes and taking out engines. Over the last few years, I've learned a little bit of body work from my colleagues.
And yes, on Wednesday I finally got to see the paint I've been dreaming about the last few years. I present to you, the first W203 in 934 Chinablue!
I figured you had some type of mechanical knowledge. I’m sure the other guys love you being there and taking care of the electronics and mechanicals for them.
Oh, i totally forgot to update this thread.
I serviced the engine, before installing it.Changed the rear main seal, valve cover gasket, changed all rubber hoses, swapped all spark plugs, resealed the lower oil pan and did an oil change. Compression across the cylinders were all fine and the o ring behind the timing cover was changed in 2018.
In July after the chassis was painted i stripped the interior, cleaned everything up and then sprayed it in china blue too. I wanted the car to be painted in blue, like it came out of the factory.
I redid the whole brake system on this car too. The brake hoses are braided, the brake lines are from KuNiFer and are a copper, nickel and ferum mix, so they don't corrode anymore. Bending the whole lines from front to back was quite the task. Rear calipers are from the CLK63 (Black Series) and front brakes are from the W204 C63 (this caliper was also used in the CLK63 BS). Timewise this was around August to Sptember.
The last weeks i was doing some paint prepping on the body parts, which had to be painted, since i finished all the rest on the car. I want to do a full chrome delete so i got a set of classic trim pieces for the doors and rear bumper. Unfortuntely you can't swap out the front bumper trim, since it's poured into the bumper, so we had to get creatice. I filled the chrome clip are with 2k glue and sanded it all down and afterwards we put some plastic filler over it. The painters started painting the parts this week and should be finished next week. After that i can finish putting eveything back together I also decided on what rims to run on this car and went with OZ Superturismo in 19". I have to use 44 offset on the front like the W204, because of my wider wheelhubs, since i have C63 front knuckles with C63 brakes.
