The Geman Cars are desirable, but the quality lacks quite a bit and then they very expensive to fix.
Don't know why your comment was downranked so much, you're completely right. Check multiple reliability surveys, Japanese cars always come out on top, and more frequently Korean cars too. My German-auto owning friends who buy and repair Audis and Mercs as a hobby even admit that the cars have spotty reliability. They like the tank-like feeling of the cars and the handling, but in terms of reliability and repairs they're a mixed bag.
