You can also do a search on "buying clk" and find several prior responses on buying and info associated with particular models.
welcome and good luck....




The 07 should be outside the range of MY (model year) for most of the common failures.
I'd get a PPI from an MBZ dealer, and specifically ask them to check service records to see if this had been repaired under warranty. If not, then check stored ECU codes to see if it has P0016 and/or P0017. If so, walk away. Keep in mind that these sprockets often failed early, but there are still some that don't fail until after 100K miles.
If this one was never repaired and there are no stored codes and you decide to roll the dice, I'd do two things: First, negotiate with the seller because of this. Second, consider and extended warranty that would cover the repair - it's expensive, about $4K.
