Classic line
The Classic Line represents classic Mercedes-Benz models refined with a subtle, modern touch. Even body modifications, such as widening, are always based on the vehicle's original design. This ensures that the proportions, character, and historical appeal are preserved while the vehicle is carefully and contemporarily evolved.
// 02
Modern Line
The Modern Line follows a unique approach, where the character of the base vehicle is purposefully highlighted and evolved. Widened bodywork, sharp edges, clean lines, and precise transitions give the vehicle more expression and presence without masking its origins. The result is a modern, powerful, and stylish reinterpretation.
4K Werk stands for exclusive Mercedes-Benz refinement at the highest level. Made in Germany is part of our commitment
