Mercedes S-Class reliability - better info
TrueDelta reports absolute repair rates that make the differences between cars much clearer. Results are updated four times a year, to report on new models quickly and track cars closely as they age.
We currently provide results for a few Mercedes models, but the S-Class isn't included in the survey yet. For a model year to be included, at least 25 owners have to sign up to participate.
Participants simply report repairs the month after they occur on a one-page survey. When there are no repairs, they simply report an approximate odometer reading four times a year, at the end of each quarter.
To encourage participation, participants receive full access to all results, not just those for the B-Class, free of charge.
For the details, and to sign up to help out:

I should clear one thing up that frequenly needs clearing up. The main survey covers from 1995 on, but has a minimum sample size.
The other surveys have no minimum sample size but require specific powertrain information, and I've only entered back to 2002 so far. I'll be adding earlier model years, just need to find the time to do it.

Those of you who have signed up, I appreciate. Still not enough to inclue the W220 in the main survey, but the 2000 is now over halfway to the minimum, and others aren't far behind.
I've also been working to get the BMW 7 included, so we'll be able to compare the two models. They're a bit further along, with 91 cars signed up vs. 85 for the S-Class.

Now 111, and the 2007 will be included in the survey this month.
Among the W220s, the 2000 is closest--currently ten cars short of the minimum.

We've started providing new stats for the odds of requiring no repairs and the odds of having 3+ repair trips in a year's time. Just a matter of getting enough owners involved.
The first set of these new stats:

To provide an additional benefit, I recently enhanced the related repair history survey so that it can (optionally) be used as a personal car maintenance record.
Now only six owners short of the minimum with the 2000, and only ten short with the 2001. And a couple of other years are now halfway.

Just a few short of the minimum needed to get started with the 2000, and other years also getting closer.

The 2000 has been added to the survey. Thanks, guys. It is right at the minimum, so additional participants would be very helpful.
Now also just five short of getting started with the 2001.

Some owners have reported that they no longer have the car the enrolled, so we're again a few cars short of the minimum with the 2000. We might still have a partial result for the 2000 in August, but it's going to be close. Even a few additional participants would be very helpful.

Didn't quite have enough responses for November. Hoping to get there for the February update. Currently a couple responses short of the minimum for the 2000.
Even a few more participants would make a big difference.
