Technic Mercedes-Benz Arocs 3245 Truck 42043

The LEGO Technic Mercedes-Benz Arocs Truck 42043 was first introduced in 2015. With 2,793 pieces, it quickly became a favourite among enthusiasts for its complexity and realism. This set is now retired and can only be found sealed and original from BuyMyBricks.
In depth

The full description

The LEGO Technic Mercedes-Benz Arocs 3245 Truck (42043) is a retired engineering masterpiece that brings a full-scale heavy-duty vehicle to life through precision construction. This sealed set represents a significant piece of LEGO Technic history, a complex, satisfying build that’s become increasingly difficult to find in original condition. Whether you’re a dedicated Technic collector or seeking an ambitious building challenge, this is a set that delivers on both fronts.

What You Get

  • Complete factory-sealed LEGO Technic set 42043
  • Authentic Mercedes-Benz Arocs 3245 truck design with realistic proportions
  • Advanced mechanical functions including working steering, suspension, and motorised elements
  • Detailed cab and functional cargo bed for authentic play and display
  • Comprehensive instruction manual for guided building
  • All original components verified present and accounted for

Why This Set

LEGO Technic sets of this calibre are built for builders who appreciate authentic engineering. The Arocs 3245 demands patience and precision, you’re not simply snapping bricks together. The build process teaches mechanical principles through hands-on experience: understand how steering articulation works, see suspension respond realistically, and grasp the logic of power transmission. It’s genuinely educational.

Once complete, the finished truck is a striking display piece. The scale, detail, and structural integrity mean it looks equally impressive on a shelf or in a display cabinet. This isn’t a set that disappears into a box after building, it commands attention. The Technic aesthetic, visible gears, exposed mechanisms, functional parts, makes it inherently more interesting than static models. Dust doesn’t bother it; the engineering actually shows off better when you can see inside.

Condition Guarantee

This set is factory-sealed and verified by BuyMyBricks. We handle retired LEGO exclusively and understand what collectors expect. Every element has been checked to ensure nothing has been opened, used, or damaged in storage. You’re receiving the set exactly as it left the factory. We stand behind that guarantee, every piece is accounted for and in pristine condition.

With a sealed set, you also get the original printed materials, untouched instruction booklet, and the satisfaction of opening and building a piece of LEGO history yourself. That experience has genuine value that mass-produced new stock simply cannot replicate.

Shipping & Returns

Free tracked UK delivery on orders over £85. If for any reason you’re not satisfied, returns are available within 30 days of receipt, no questions asked.

Common questions

The things people ask

Is it genuine and factory sealed, and what if it is not?
Every set is checked before it is listed: the factory seals and tape first, then the corners and edges, and anything worth knowing about the box goes on the listing. If a set from us is not genuine and factory sealed, tell me and I refund in full and pay the return postage. We sell sealed retired sets and nothing else, so there is no opened or used stock for yours to get mixed up with. Returns for any other reason are within 30 days, sealed, as the returns policy says.
When will it arrive?
Order before 3pm on a working day and it goes out the same day, tracked and insured. UK orders arrive within 1 to 3 working days, and you get the tracking number by email as soon as it is on its way. Tracked UK delivery is free over £85.
How is it packed, and what if the box arrives damaged?
The set box travels inside a second carton with fill, so the courier handles the outer box and not the one you are keeping, and every parcel is insured to its full value. If it still turns up damaged, photograph the outer packaging and the set box before you unpack any further, then email support@buymybricks.com with the photos and your order number the same day. We reply the same working day with a replacement if we have one or a full refund, and we deal with the courier claim ourselves so you do not have to.
Do you ship outside the UK?
Yes to the United States and Canada, with tracked and insured delivery costed at checkout before you pay. We do not ship to the EU at the moment. Everywhere in the UK is covered by the standard tracked service.
Can I return it?
Yes, within 30 days of delivery. If it arrived damaged or not as described, tell us and we pay the return postage and refund in full or replace it. If you have simply changed your mind, the set needs to come back sealed and as it arrived, and the return postage is yours. The refund goes back to the card you paid with within 3 working days of the set landing back with us. Use a tracked service so there is proof of delivery.
Is there a discount code?
Yes. Join the email list on any page and your first-order code comes through in the first email, along with what has just landed. We do not print the code on the site, so the list is the way to get it.
Can I pay in instalments?
Yes. Klarna Pay in 3 is at checkout: three equal payments, no interest and nothing extra to pay. Visa, Mastercard, American Express, PayPal, Apple Pay, Google Pay and Shop Pay are all there too. Payment is handled by Shopify Payments and we never see your card details.
Is it going to be a gift?
Tell us in the order notes at checkout and no prices or invoice go in the parcel. Sending it straight to them is fine: put their address as the delivery address and keep yours as the billing address.
Can I have a VAT invoice?
Yes. We are VAT registered and every price on the site already includes VAT. Reply to your order confirmation asking for one and it comes back the same working day. For a business or bulk order, email support@buymybricks.com before you buy and we will sort an itemised invoice.
Not the set you want?
Tell us the set number and we will look for a sealed one through the trade. If we find one at a sensible price you get an email with the link before it goes on the site. Ask us to find it.

Not answered here? Email support@buymybricks.com or ring 01904 900212. A person reads it, usually the same day.
