I have about 230 000 km on the clock.

Is replacement of the mounts a DIY job? Is there any DIY directions on how to do on C280 with V6 motor. Found directions on the straight 6 (M104) but apparently V6 is more tricky.

Also, I can get "replacement" (pirate) mounts for about 1/3 of the price. Are the mercedes ones that much better. Are the mounts for the M104 and m112 the same part - that whats the "pirate" catalog says.
