Hello, I bought a Smart CDI at 2 years of age TÜV. Rather as a transitional car, it was not really expensive, 2700 euros with new TÜV. The car has already drained several thousand KM and never a problem. So it was totally worthwhile for the money. But in the interior I discovered rust. The rust is inside in the windshield in the middle, that comes out through the seal, but it is absolutely everything tight. It is not dramatic, but what to do? Thanks and greetings.
