Should You Buy the 1994 Mercedes-Benz G-Class?
The 1994 Mercedes-Benz G-Class, specifically the W463 generation, is an exceptionally rugged and iconic vehicle, a true testament to over-engineering. While its core mechanicals are incredibly durable, ownership demands a significant financial commitment and specialized care to address the inevitable age-related issues, particularly electrical gremlins and pervasive rust.
