Platform Heritage

The Mercedes-Benz G-Class, colloquially known as the G-Wagon or G-Wagen (as an abbreviation of Geländewagen), is a four-wheel drive luxury SUV sold by Mercedes-Benz. Originally developed as a military off-roader, later more luxurious models were added to the line. In certain markets, it was sold under the Puch name as Puch G until 2000. The G-Class is characterised by its boxy styling and body-on-frame construction. It uses three fully locking differentials, making it one of the few passenger vehicles to have such a feature. Despite the introduction of an intended replacement, the unibody SUV Mercedes-Benz GL-Class in 2006, the G-Class is still in production and is one of the longest-produced vehicles in Daimler's history, with a span of 46 years; only the Unimog surpasses it. In 2018, Mercedes-Benz introduced the second-generation W463 with heavily revised chassis, powertrain, body, and interior. In 2023, Mercedes-Benz announced plans to launch a smaller version of the G-Class, named "little G"—though no definitive date was given for the launch. The 400,000th unit was built on 4 December 2020. The success of the second-generation W463 led to the 500,000th unit milestone three years later in April 2023. The 500,000th model was a special one-off model with agave green paintwork, black front end, and amber turn signal indicators in tribute to the iconic 1979 press release photo of a jumping W460 240 GD.

  1. Verify OBD-II readiness monitors are complete (not recently cleared) using a full protocol scan.

  4. Run a MotoMetrics on-site scan for Mercedes-Benz G-Class before signing the bill of sale.

Vehicle health varies wildly by individual history. Aggregate recall and complaint data cannot tell you whether the specific car on the lot had its monitors cleared or its odometer rolled back. Verify the physical or digital scan before you sign a bill of sale.
