My 98 W210 (V-6) has about 120k on it, and I want to replace the SPARK PLUGS and some other maintenance parts. Just wondering if there is any trick to replacing the SPARK PLUGS, or there is anything I should be prepared to do or not to do.
Any advice will be greatly appreciated.

If I may..... I also read the discussion about the SPRING PERCHES on the E300/320 which many have reported broken while driving. I was just wondering if anyone has an update on this problem, especially from Mercedes Benz.

Thanks and Happy New Year To Everyone.
