Mercedes S-Class reliability - better info

[mkaresh]

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: Car reliability research

64 S-Class owners signed up so far. A decent start, but more are needed to include the S-Class in the survey.

Now 74. Getting there.

theyre all for 2002 and newer reviews, i joined but my 2000 will obviously not be included as it wont even let me take the surveys

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 93 for the S-Class, vs. 97 for the 7. Oddly, we have more owners signed up for the Lexus LS than for either of the German cars--118. Looking forward to having results for all three.

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.
