100 euros below the MSRP: Smyths Toys is currently offering the large LEGO Technic Mercedes-Benz G 500 PROFESSIONAL Line for 149.99 euros. The manufacturer’s suggested retail price is 249.99 euros. That works out to a 40% discount —and that’s exactly the kind of deal that makes me take a closer look at LEGO Technic sets.
What’s behind this deal?
The off-road vehicle, set number 42177, consists of 2,891 pieces. It features working steering, suspension, a replica inline-six engine, a three-speed transmission, and differential locks. For Technic fans, this isn’t just a small side project—it’s a full-fledged model.
As of the check on October 21, 2026, Smyths lists the item as in stock for 149.99 euros and offers free standard shipping. Click here to go directly to the deal at Smyths Toys. Prices and stock levels are, of course, subject to change at any time.
Is 149.99 euros already the best price?
No—and I think that’s important. Our Brick-Tracker Price Comparison shows that the model reached a historical best price of around 134 euros in November 2025. So 149.99 euros is a very decent current sale price, but not a new all-time low. That’s exactly why, before making a major purchase, I don’t just look at the percentage off in the retailer’s banner, but always check the Price History as well.
Why is this set interesting for LEGO investors?
Brick-Tracker currently lists the Mercedes with an estimated EOL date of 2026. This is a forecast and not an EOL date guaranteed by LEGO. If the model does indeed disappear at the end of the year, buying it at a 40% discount could be a great deal—especially if you plan to resell the set later.
Personally, I prefer to wait until discounts reach about 35 to 38 percent—or better—before buying in larger quantities. At 40 percent, the Mercedes clears this first hurdle. But the discount alone doesn’t make for a good investment purchase: the key factors are demand, competing offers, potential successor models, and the question of how much capital and storage space I’m tying up. A large Technic box also incurs different shipping costs than a small Battle Pack.
My conclusion: For me, this is an absolutely top-notch set
Personally, I see the LEGO Technic Mercedes G 500 as a really solid Investment. I find it particularly exciting that, this late in the year—just before its expected EOL in 2026—we’re getting another 40% discount. For me, this is an absolute must-have set. I’ve already placed an order for a few sets myself and have the Mercedes in my own inventory. Given this deal, I can therefore wholeheartedly recommend snapping it up while the price and availability are right. Of course, future value appreciation remains to be seen; the EOL classification is a forecast, not a guarantee.
Why isn’t Smyths Toys listed on Brick-Tracker?
There’s one thing in particular that bothers me about this great deal: Unfortunately, Smyths Toys isn’t yet integrated into Brick-Tracker as a Seller. I’ve already tried to get in touch with Smyths to set up a partnership or a technical integration. So far, that hasn’t worked out. If anyone in our community can put me in touch with the right people at Smyths, I’d really appreciate the help. It would be a dream come true if we could display Smyths in Brick-Tracker in the future as well!
