We maintain an absolute skeptical attitude. In addition to regular visual inspections, we focus on checking for sediment accumulation around the sunroof drainage channels and look for water stains under the A-pillar trim and front floor mats. This is the only effective physical evidence to determine if the sunroof drainage holes are blocked, leading to hidden leaks.

We will honestly inform you of the common issues with this model (such as the water pump failure in certain German cars) and show that this car has had the improved parts replaced.

Absolutely not. Any secondary damage caused by overseas non-professional repairs, violent disassembly, or the use of inferior replacement fluids will immediately void any form of "extended parts compensation" we provide.
