Maintenance question???
 

Hi my name is joules I'm from Houston, I don't have a MB yet. I'm planning on buying a pre owned GL and don't have any knowledge on Mercedes. I have my eye On a 07 GL with a 70xxxmiles my concern is about maintenance schedule since mileage is a bit higher.

Normally at what miles does it needs oil change and for major maintenance like 100k miles how much does it usually cost.

Tnx in advance...
