gomez, what dealership do you go to? In Central Jersey I think there are only three choices....Contemporary, Catena and Davis. I have not heard great things about catena and I use Contemporary when I need a dealer. Otherwise, I have a private shop for regular maintenance.
Rough Idleing on a W210 might be the Harmonic Balancer. There is a recall out for that part. Call a Dealer and give them your VIN. They will be able to tell you if you car is affected.
My car started idling rough about two months ago (98 E430 86,911k) and I thought it was the plugs too. They are 100k plugs and mine have not been replaced. I was going to have that done when I learned about the HB issue. turns out my car is affected and I have an appointment in 2 weeks to have it replaced. I checked it out and I don't seem to be having any major deviations in it right now (at least that I can see) as compared to some of the HB pics I have seen.
GL with your car. Let me know if you need any other info on dealers. I live in Monmouth County on the shore side.

Harmonic balancer isn't a problem with the inline-6 motor.
If the motor vibrates but isn't misfiring, it could be motor mounts.
If it's misfiring, could be any number of problems including mass airflow sensor, plugs/wires, ECU, etc. Is the check engine light lit?

a 97 E320 takes virtually no mechanical skill to replace the plugs. I replaced mine at around 90,000 miles and gained around 4 mpg and the car purred like a kitten. This is good preventative maint and can be done in your garage in about an hour.
However, it may not be the cause of a rough idle so be prepared for the other usual suspects like MAF, O2 sensors, motor mounts, etc...
You can search this forum on very detailed instructions on changing all of these parts.

The 97 is an inline 6? Didn't know that.
I am somewhat mechanicly inclined, but it has more to do with wood than grease and metal. I can make you a chair, a table, and finish all the molding in your house, but I look at a car and break into a cold sweat at the thought of doing anything more complicated than cleaning it.
When I replace the plugs, I want to replace the wires as well. And that is a job I know I am not capable of.

I was referring to both plugs and wires. The wires are the easy part of an already easy job. Keep in mind that I live in a condo, have a mediocre tool kit and have no mechanical skills. Think of removing a spark plug like removing a lug nut from your wheel. The wires are just unplug the old wires and replug the new. There's a detailed post somewhere on here about doing it if you care to search for it. It's a very satisfying job, you get to get your hands dirty, it's super easy and your car will perform beter and love you for it.

The V6 is a different beast. mgraeff -- the one who wants to replace his plugs -- has the V6. The difficulty with the V6 is twofold: (1) there are 12 plugs, and (2) it is very difficult to disconnect the wires from the plugs unless you've mastered the technique. You have to grasp the base of the plug wire boot with one hand and use an open-end wrench in the other as a lever against the valve cover to pry the wire off. Unlike the inline-6, there is limited room around the V6 and you can't easily see what you're doing. You also have to beware of loosing the screws that attach the coil packs to the valve covers, since you have to move those out of the way to access the plugs.
Replacing the wires on the V6 is very easy. You disconnect the wire from the spark plug end anyways. All you have to do beyond that is remove the other wire end from the coil. I can't imagine that would be difficult at all.

Lol I have a V8 so I have 16 to worry about. The post above has scared me straight. To the mechanic it goes for plug and wire replacements. :p

I also have a '97 and find that motor vibrates a little too much. I have been told the motor mounts need to be replaced. If you do a little research, I think someone on this site was able to it himself.

Don't throw good money after bad. Find a good MB mechanic and have the problem diagnosed. Your mechanic may charge you an hour labor but probably won't mind if you tell him that you want to try to fix it yourself. I think you could drive yourself crazy and broke if you keep chasing a very broad problem like a rough idle... my 2 cents.
