Hello friends of the old SLK, maybe I have too high demands on the seats on the SLK or generally also on the 210er, 208, and all Benzer from the mid-1990s. Hope I can give you a tip if I can improve this myself or if by upholstery in the specialized company the seat becomes tight and smooth again because then I would like to take the money in the hand. The vehicle was registered in mid-1999 and thus the preFL version with the old seats. The cars from FL are also not better in this area except that the more side support offers. However, the vehicle only ran just over 48 tkm and I don’t know if the previous owner was a heavyweight and the seat therefore looks like this. The passenger seat is almost like new, hang pictures. The vehicle has been in my possession since 2019 and I had expanded the seats over the winter and cleaned in the basement and treated with care products. Actually the whole interior was a If desired, I can arrange a manual including pictures of the repair of the roof cylinder including needed parts and tools as well as the roof sky with Alcantara and the painting of the entire grey plastic parts in anthracite so that it also fits together. I had already completely disassembled the seats of another SLK and repaired defective seams so that i under the seat heating a 15 mm upholstery is installed and possibly this can be tensioned again by a thicker upholstery. But first I hope now for your help or opinions, thank you.
