The first generation chairman was built on the Mercedes-Benz E-Class (W124) platform,[citation needed] but styled more like a modernized W140 S-Class.

[citation needed] Coincidentally, the design also foretold that of the upcoming W220 S-Class, which led to some consternation at the German company.

The 2005 Chairman, based on the Mercedes-Benz E-Class (W124) had the following features: heated and cooled cup holders, rear parking sensors, rain-sensing wipers, anti-lock brakes, stability and traction control.

Chairman W is offered in six trims with two engines, a limo version, and an additional AWD 4-Tronic (Mercedes-Benz 4Matic).

It has an electronically controlled self-levelling air suspension system with a rebound coil that helps reduce noise and vibration, as well as an extended rear passenger space[4] and the front and rear both have their own screen to control the car's entertainment system, similar to Chrysler's MyGig.
