Designed for young engineers but adored by adult Technic fans, it’s both playable and display-worthy.
Investment-wise, it’s a steady performer — rising from $150 to $240 over five years (60% growth at RRP, around 129% at the sale price). As LEGO’s new “Space 2025” range continues to expand, early Technic models like this could become collector favourites.

The adjustable handle and self-levelling cockpit add even more realism.
Predicted to climb from $110 to $176 within five years (60% at RRP, a huge 167% gain if bought now), this set is arguably the best short-term flip of the sale, particularly given its 40% discount and strong appeal to Technic and space collectors alike.

The buildable platform includes rotating turntables and a leap function, with five detailed minifigures — including Ahsoka, Ezra Bridger, and Thrawn — making this a perfect mid-size display piece for fans.
Projected to rise from $55 to $75 in five years (36% at RRP, roughly 127% at the sale price), it’s an accessible entry point into LEGO Star Wars investing — and one that’s likely to gain collector traction once the series’ second season arrives.

Final Thoughts: The Perfect Time to Buy

All of these featured sets are due to retire by the end of 2025, meaning they’re already in their final months of production. Once LEGO ceases manufacturing, prices historically spike — particularly for well-reviewed, collector-driven sets like these. Combined with discounts of up to 40%, this sale window is the ideal time for LEGO investors and fans to act before stock disappears.

Whether you’re building your collection or buying for future growth, there’s rarely been a better time to shop. Head to LEGO.com or Amazon’s Prime Big Deal Days listings to grab these sets while they’re still available.
