Ok fellow GLA owners. As of February, my warranty was up. That means, the dealership just lost my repair/maintenance business. Is there anyone out there doing their, own maintenance/repair work? I am getting ready to do a major repair with my father in law. Mercedes quoted 8k on a rear differential swap. I found a salvaged Rear differential for $450. After buying new seals, and fluids, it looks, to come out to around $650 in parts. My wife and I both had mid 2000s Jettas, lasting almost 300k miles on each. My father in law, has done major engine repairs, and suspension repairs on both. So my question is, who was worked on a late model Mercedes, and how hot is the fire, we are playing with?
