I did the one on my W124, its a lot of work and time, not hard just all the fiddly things that have to come apart, the complete dash has to come off, I'm sure the R129 has more stuff! hardest part I had was removing the heater box, while I had it all apart I replaced evap , heater core, all vacuum elements for HVAC system, about 8 hours for removal and 6 for reinstall, I have knowledge on air condition systems, tested and refilled my system, my total cost was around $500 in parts, I'm sure SL parts will be more, a dealer or indy could charge big time! 2-3K or more, but it can be done in your home driveway!
