We've updated our reliability stats for the GL-Class to include owner experiences through September 30, 2014.

Repair frequencies, in terms of repair trips per 100 cars per year:

2014 GL-Class: 25, low, very small sample size
2008 GL-Class: 93, high, small sample size
2007 GL-Class: 93, high, very small sample size

Additional participants would be very helpful. (I'd love to be able to drop the disclaimers and cover all model years.)

We've updated our reliability stats for the GL to include owner experiences through the end of 2015, about eight months ahead of other sources. In terms of repair trips per 100 cars per year--lower is better:

2015 GL: 23, low, very small sample size
2014 GL: 39, moderate, small sample size
2008 GL: 89, high, small sample size
2007 GL: 69, moderate, very small sample size

With more participants, we could provide more precise stats and cover all model years.
