First, THANKS to everyone who answered today!
Short of some C4 or pushing it off a cliff Im not sure what to do with it! I replaced the radiator today witha new one. Flushed out the sytem etc etc. Its now running a little hotter than before!
Ive replaced:
Clutch
Sensor
Thermo
Radiator

I love this car though I know its the poor guys Mercedes and want to get it right. Im just so perplexed at this point!

Thanks for anything you can give!!!
**on a positive side the changing of the strut mount went very smooth today :-)
