Another suggestion for Maybach's struggles was that parent Daimler had failed to differentiate it from its Mercedes-Benz brand. While all three ultra-luxury marques share platforms and engines with other luxury brands from their parent auto company, Maybachs are built alongside the Mercedes-Benz S-Class flagship sedan, whereas Rolls-Royce and Bentley are assembled in England (separate from the rest of BMW and Volkswagen Group's respective production plants), and thus are regarded as being more "exclusive". Furthermore, the Maybach's pedigree was virtually unknown outside of Germany, unlike its British rivals which have long enjoyed renown worldwide; indeed the 2006 Rolls-Royce Phantom's interior evokes memories of a 1930s car while the Maybach 57S's inside makes no reference to its marque's history.
