It is heavily based on Mercedes-Benz mechanicals, utilizing a platform derived from the W124 E-Class but stretched to provide limousine-like rear legroom.

Powered by a 3.2L Inline 6-cylinder petrol (Mercedes-sourced M104) paired with a 5-speed Mercedes-Benz automatic.

Common features are reclining leather seats, airline-inspired tray tables, and heated/cooled cup holders.

Rear passengers can electronically slide the front passenger seat forward for extra legroom and control the audio/climate systems.

It also includes a 10-speaker premium sound system, adaptive dampers, and memory seats for the driver.

In Western markets like Australia, the 2005 Chairman struggled due to its lack of brand prestige compared to established luxury rivals like BMW or Mercedes-Benz. It was extremely rare, with only about 100 units reportedly brought to Australia between 2005 and 2008. Today, it is noted for its rarity and the value it offers on the used market as a budget "executive" vehicle.
