I wanted more up-to-date car reliability information that made the differences between cars clearer. So I started TrueDelta, which now updates actual repair frequencies, not just dots, four times a year to track cars closely as they age.

We've been providing reliability stats for the first-gen GL-Class for some time now. Will the X166 be better?

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, following the end of each quarter.

To encourage participation, participants receive full access to all results, not just those for the GL-Class, for free. I'll share results for the GL-Class in this thread once we have them.

For the details, and to sign up to help:
