1992 Mercedes-Benz ML270

The M-Class was the first luxury SUV to feature stability control, a system designed to detect loss of control and instantaneously intervene with selective braking to bring the vehicle back on its intended course. This system is now hailed by safety experts, and studies have shown stability control and systems like it are capable of reducing single vehicle crashes by up to 30 percent. Furthermore, the M-Class boasted front- and side-impact airbags with advanced occupant detection for the front passenger seat, which, combined with Mercedes' legendary safety structure, earned the M-Class the highest marks in insurance industry crash tests.

Aroad test on the BBC programme Top Gear revealed that the presenter, Jeremy Clarkson, could put his fingers into the gap below the rear lights and above the rear bumper. This improved over the years, especially after a mild facelift for 2002. However, owners are often unhappy with the car's quality — for example, the car was placed last out of 142 cars in the Top Gear Motoring Survey 2004. DaimlerChrysler spent US$600 million on improvements at the Alabama factory before launching the second-generation ML in 2005.
