CLAAS XERION 5000 TRAC VC

"With a BrickScore of 87.5, the CLAAS XERION 5000 TRAC VC earns near-universal acclaim as one of the best Technic sets LEGO has produced — its three-mode steering alone is considered a mechanical masterpiece, and the total package of functions, scale, and looks is hard to beat at its price point."

The CLAAS XERION 5000 TRAC VC is celebrated across reviewers as one of the finest Technic sets ever released, praised for its exceptional engineering and sheer breadth of working functions. Reviewers consistently highlight the three selectable steering modes (2-wheel, 4-wheel, and crab), the rotating cab, crane/grapple, and modular attachment system as standout mechanical achievements. The build is described as challenging but deeply rewarding, with the finished model being notably large, robust, and visually striking in its lime green and black colour scheme. Minor criticisms exist around mechanical slop and cab/crane stability, but these are widely considered trivial against the overall package.

Where they split: Value-for-money scores split noticeably: most reviewers rated it 100/100 on value, but at least one scored it 40/100 — likely reflecting the higher secondary-market price after retirement. The B-model also drew split opinion; some found the alternate attachment worthwhile, others considered it underwhelming compared to the A-model.
