To answer the question about auto costs in the US -- Japanese cars (even luxury cars) are cheaper than the equivalent German cars, and are widely recognized as "better" in quality and practicality, but not in style. The Japanese cars tend to denigrated as "bland" and the Japanese luxury cars, like Lexus, as looking like bloated small cars. That may be going away a bit with the latest designs. In the latest issues of the American consumers magazine, Consumer Reports (the special car issue), Mercedes Benz are ranked among the lowest in quality of the major brands, with serious quality control issues with both brakes and transmission. I own a CLS, and I agree; I hate the brakes, and the transmission, already fixed once under warranty, sounds like it will be going back for a second try. Another aspect in German car costs is that only certain Mercedes are imported to the US -- I'm in Vienna at the moment, and I see all kinds of MB here that we never see in the US. In the US, most MB are considered upper-rank cars, while in Europe there are MB models that are commonly used as taxis. And finally, German cars are much more expensive to maintain than Japanese cars. I have to make a right-angle turn to get into my garage, and I recented bumped the back of a heavy riding lawnmower with the left bumper of my MB. No damage to the John Deere mower, but I had a tear in the plastic skin on the bumper, and a broken piece of plastic bumper itself, about the size of a penny. Estimate to fix: $3500.
