The Mercedes-Benz M-Class is a 4-door SUV with light off-road capability, first offered in 1997, and built in Tuscaloosa County, Alabama, USA, at the same time as its competitor, the Infiniti QX4. It marked a shift at Mercedes-Benz in becoming a global player; while it had plants outside Germany before, they merely built facsimiles of German models. In contrast, the M-Class was conceived with the American market in mind and built at an American factory. Despite early negative press about quality control, the M-Class became a huge sales success in the United States. In fact, only the C-Class and E-Class sell better in the US.
