We have updated results for the E-Class to include owner experiences through June 30, 2011.
Repair frequencies, in terms of repair trips per 100 cars per year:
2007: 62, about average
2006: 49, better than average
2005: 71, about average
2003: 130, about average, very small sample size
We'll have further updates in November and February. With more participants, we could provide more precise information and cover all model years.

We have updated our reliability stats for the C-Class (on our redesigned site) to include owner experiences through September 30, 2011.
Repair frequencies, in terms of repair trips per 100 cars per year:
2007: 60, about average, small sample size
2006: 79, about average, small sample size
2005: 90, about average
2004: 102, about average, very small sample size
2003: 80, better than average, small sample size
2002: 79, better than average, small sample size
Quite consistent from year to year this time despite the often small sample sizes.
Thank you, once again, to everyone who has been helping. We'll have further updates later this month and in May. With more participants, we could provide more precise information and cover all model years.

We have updated our reliability stats for the C-Class to include owner experiences through September 30, 2012.
Repair frequencies, in terms of repair trips per 100 cars per year:
2007: 49, about average, small sample size
2006: 92, worse than average, small sample size
2005: 53, about average
2004: 73, about average, very small sample size
2003: 78, about average, very small sample size
2002: 80, about average
Quite consistent from year to year this time despite the often small sample sizes.
We have two additional statistics, "Nada-odds" and "Lemon-odds," to indicate the percentage of cars with no repairs in the past year and those that required 3+ trips to the repair shop.
With the 2008 the percentage with no repairs is about 73, while the percentage with 3+ repair trips is less than 1.
We'll have further updates in February and May. We'd love to provide more precise stats and cover more model years--just a matter of getting more owners involved!

2001 C240
Thanks for the reliability updates on the C-Class. A rating of "about average" is not bad for a 10 year old W203. In the early years of ownership I had some electronic and one suspension bushing issue. Some paint peeling on the lower doors which I touched up with Rustoluem and touch up paint. But other than that my 2001 C240 is quite a solid car.

I wish we had a stat for the 2001, but not enough owners have been responding. Just a few short, so additional participants for the initial model year would be very helpful.

Depends on how he's working the data.
There would be fewer 2002's on daily driver duty at this point, so miles per year would be less than the newer W203's, I'd guess. Hard to tell from the way he presents the data.
Still, 2002's have a fairly spotty repair/rust record, from any standpoint. All of you 2001 owners should be happy there's not enough data to post a result.

Sounds like we've got a glass half full / half empty situation here. One person shocked that the stat for the 2002 is nearly one per car, another surprised that it's not higher.
One thing to remember: this is all repairs, not just major ones.
In my personal experience a car starts seeming unreliable these days when it goes less than a year between repairs. This feels like "all the time."
tommy brings up a good point. The stats seem to stop getting worse for many models once the cars are about a decade old. Two factors are probably responsible. As tommy notes, people stop driving cars as often once they reach a certain age. On top of this, they probably start letting more small stuff slide instead of getting it fixed, and this stat measures things that are fixed.
On the site we post the average odometer reading, but we haven't tried to calculate and report the number of miles driven in the past year. This might be something we should start doing, if the data permit it.

No, like last time we were a couple of responses short of the minimum.

2002 C230 Coupe
Reliability is a strange word to apply to my car -- rescue dog would be more appropriate. 2002 C230k coupe, bought for low book with lots of stupid malfunctions, like remote didn't work because of missing fuse for the receiver, parking brake didn't work because cable was disconnected....

It's been a long time, I know. But I've added the C200 CDI powertrains (manual and auto) to the database for the C203. It looks like there was a slight power bump in 2003.5.
