Review - LEGO Technic Mercedes-Benz G 500 Professional Line (42177)

The LEGO Technic Mercedes-Benz G 500 Professional Line (42177) captures the rugged elegance and engineering precision of the real vehicle in an impressively detailed Technic build. I had a great time (mostly) building this and the end result is impressive.

Pros

• Looks great & impressive size: The finished model has real shelf presence. It’s proportionally accurate and instantly recognizable as a G-Class.

• Understandable features: The mechanisms are clear and logical, making it satisfying to see how everything works once assembled.

• Door locks: A small but very cool detail, these add realism and a premium feel.

• Colour choice: The orange bodywork looks excellent, highlighting contours and giving the model a realistic finish.

• MOC / C-Model potential: There’s excellent potential for reusing parts, many great MOCs are already available on Rebrickable that make use of this set.

• Value for money: I paid $200 (half RRP) for a brand-new set, which made it an absolute steal. Even at full retail, the part count, design, and final result justify the price.

Cons

• Lengthy, occasionally confusing build: Some steps require careful attention and may frustrate less experienced builders.

• Clearly aimed at adults: While not necessarily a bad thing, this isn’t a beginner-friendly Technic set.

• Tight lever access: Some feature controls are a bit awkward to reach once everything’s assembled.

• Weak door connections: The doors have a bit of flex, especially near the top, which slightly detracts from the solid feel of the model.

Overall

The Mercedes-Benz G 500 Professional Line is a fantastic Technic set, a strong combination of looks, functionality, and value. It’s both a rewarding build and a striking display piece. For anyone serious about LEGO Technic or looking for a premium, realistic model with excellent MOC potential, this is a must-buy.

⭐ Rating: 9/10 – Great design, great value, and a joy for any Technic enthusiast.
