Our Take
Why we rate
this set
this set
BuyMyBricks editorial
This is a serious build. The crane mechanism is genuinely clever — motorised or manual depending on your approach — and the engineering throughout rewards close attention. When finished, it occupies genuine shelf space: nearly 60cm long with the presence of actual vehicle design. The working suspension and steering make this more than static display; it behaves like machinery. Technic builders consistently rate this set for the balance between authentic vehicle design and proper mechanical complexity.
The Set
What you're
actually buying
actually buying
Released in 2015, the Mercedes-Benz Arocs 3245 brought Technic building to a genuinely useful scale — a 1:12.5 replica of a serious working truck, not a toy. At 2793 pieces, it demanded proper building time and rewarded patience with functional detail: a working crane on the cargo bed, realistic suspension, and a cab that felt substantial in hand. Builders appreciated the engineering challenge and the chance to construct something that looked like actual machinery rather than abstract mechanism.
The set's been retired since 2017, which means it's no longer stocked in shops. We've sourced a sealed example so you can still build it. What you're buying from us is a sealed, original example — sourced from verified suppliers and inspected before listing.
