Off topic. Mercedes new car extended warranty, Worth it??? Options

[daytona]

Hi,
As the tittle implies, does anyone have any information/experience with the Mercedes Benz new car extended warranty?
We just took delivery of a new E 450 4matic. The dealership is offering what I consider is a good price for the extended warranty, ad since we tend to keep our cars a long time I think it may be worth buying.
I had a bad experience with extended warranty on a new Cayman S but it was a third party warranty. This is one is actually offered by MB. I just want to know if someone here ever had to make use of it and what that experience was like.
Thanks,
Bill.

Hi guys,
Thanks for all the responses. I feel bad that I didn't include the price of the warrantee in my original post. The price is $3,200 for an additional 3 years 25,000 miles.
It does not go into effect until the factory warrantee is expired, and if I sell or in any way get rid of the car before the extended warrantee is in effect, the warrantee is cancelled and the money refunded minus a small fee.
As probably most 914 owners here, I do most of my maintenance and some of the repairs. But this car??? Other than changing the oil and maybe brake pads, a person would have to be an electronics engineer with a minor in computer networking and a knowledge of plumbing.
The dashboard gauges including the GPS screen is all one big computer display that gives me the shakes just to think of having to pay to repace it.
I am not happy with the 3rd party warrantee I had on my cayman. They didn't pay for what I expected them to pay, but they did pay for something I didn't expect. In any case, both times I had to file a claim they seemed fly by night and evasive.
Mercedes covers everything except for ware items that are spelled out on the contract.
Thank you for reminding me that the warrantees are negotiable. I'm going to give it a shot.
I know that statistically we should't buy any insurance other than health insurance. Will let you guys know how it turns out, and thank you for all the excellent comments.
