42129

Set 42129, “4x4 Mercedes-Benz Zetros Trial Truck”, represents a Mercedes-Benz off-road trial truck in the LEGO Technic theme. Released in 2021, it contains 2131 pieces and includes no minifigures.

This model brings a Mercedes-Benz Zetros trial truck into the LEGO Technic range. It belongs to the part of the theme focused on recognizable real-world vehicles and machines, where the build is shaped by structure, vehicle form and mechanical presentation rather than character-based storytelling.

The set is built from 2131 pieces and has no minifigures. Its content is centered on the truck itself, with a Technic-style chassis, bodywork and structural assemblies intended to suggest a heavy off-road vehicle. The building experience is therefore about beams, connections and functional model design, not about figure-scale interiors or scene accessories.

It suits Technic fans interested in licensed trucks, utility vehicles and models that can be displayed as well as handled. In a Technic collection, it sits closer to realistic heavy vehicles than to racing cars or fantasy subjects, offering a Mercedes-Benz truck as its main point of identity.
