Based on 33 reviews · thin
$450 for a supercar with no real secondary market legs and a build that feels like it's coasting on the badge — the Sián is gorgeous on a shelf but hard to justify on price alone.
Is the price fair?C-Four-fifty for a Technic set with no standout functions is a rough sell.
Will you love it?C-The shape is right but the build doesn't match the car's drama.
Holds its value?C-Moves slowly after retirement — not a set flippers are circling.

The Full Take
The Lamborghini Sián is the kind of set that photographs beautifully and disappoints quietly. That angular bodywork translates well in Technic plastic, and the scale is genuinely imposing — but 3,696 pieces at $449.99 is a steep ask when the interior is sparse and the functions feel routine. There's no hidden wow moment mid-build, no technique that makes you stop and stare at the instructions. The Sián lives or dies on the license, and if you're not already in love with the real car, this set won't manufacture that feeling for you. On the secondary market it's tracked sideways — not a dog, but not a darling either. A C+ is probably generous if the price had dropped a letter grade on its own.
