The guard and bumper are steel, and the guard is mounted directly to the chassis mounts, so it’s quite a bit more solid than it looks for blocking directly frontal impacts. Which is important as the oil cooler is about half an inch behind the lower bumper haha. I have an older G55, maintenance is expensive, but largely doable oneself to save money as everything is overbuilt but not overly complex. Couple electrical gremlins, front door is always saying it’s open under hard acceleration, computer thinks tail lights are out when they are not….
