Here is how a G-class withe an Audi Front design could lookl like. The Audi design looks a bit too modern considering the vehicle's overall utilitarian aesthetic. Here, you could argue that it’s the headlights that appear decently integrated into the fascia, while the grille needs to go back to something with a Q in its name.
Thankfully, nobody is going to mess up the G-Class' looks any time soon. Its styling and purpose have both remained largely the same over generations.
