Mercedes-Benz had some very lofty hopes for the Maybach, the super-luxury car it hoped would compete with Rolls Royce and Bentley. But its failure has cost half a million dollars per car. The modern-version of the Maybach, which first appeared in 1909, launched seven years ago and Mercedes thus far has sold about 3,000 of the luxury cars worldwide. But this is the final year for the car, which Mercedes announced in November it planned to discontinue. Instead, it will focus on the S-Class as its premium luxury models.
