Very good discussion.
Mercedez has been going down the hill during the last 10 years or so, mainly due to high costs. You can see their attempts to relocate to 3rd world countries to save the costs. Who could have thought, they would be making cars in INDIA.
Did any other Luxury maker of the world ever thought of doing that, NO. No Cadillac, BMW, Porche, Rolls Royce has ever rolled off an assembly line of any 3rd world country (except China, and in case of China, many of its Industrial sectors are at par with Europeans and Americans), But look at Mercedez, first they went to merge with Chrysler, a 3rd rate, firm that almost failed during early 1990s, then they went to make cars in 3rd world countries. They even have an assembly plant in Egypt.
They have realized the higher costs (in Germany) are their biggest weakness. So, may be, Germans may not be too crazy to relocate to 3rd world countries afterall. But are they compromising on their quality as well, while relocating to 3rd world countries like Egypt and India. That is up for debate.
