I went ahead and bought a gasser, now I have to deal with spark plugs for the first time in about 10 years. I have a 2001 model 210 with the M112 V6 engine. Just did a B service on it. MB states that plugs need to be changed at 5 years/100K miles for this engine. My car now has all of 42K on it.

Here's the question: Which of the following do I really need to do?
1) Nothing but drink cold beer while floating in the pool. Worry about it in another 20K miles.
2) Remove plugs, check condition, reinstall using anti-sieze. Worry about it in another 40K miles.
3) Replace perfectly good platinum plugs with new ones. Worry about it in another 5 years.

The car runs absolutely perfect. Keeping in mind that I'm lazy and cheap, and it's freakin' hot out in the garage, what should I do?

either 2 or 3... plugs can become difficult to remove after time..a large gap puts extra "tension" on the coils & wires...

I'd go with #3, but wait until it's not so frickin' hot out, in mean time go with #1, so do it but not so critical as to work up an immediate sweat.

Thanks guys, I appreciate your advice and humor. I'll pull one or two of the plugs, and depending on the condition go with door #2 or door #3 in about October...
