Comparable Set Analysis

When considering the investment potential of the LEGO Technic App-Controlled Transformation Vehicle, it’s crucial to approach with caution, especially in comparison to other app-controlled sets. The only other app-controlled set, the App-Controlled Top Gear Rally Car (42109), retired in Dec-21, initially priced at £125, currently holds a concerning valuation of £111, indicating a total growth of -11% and an annualized growth of -6%. This unfavourable performance raises a red flag for potential investors, urging them to be wary of expecting robust returns in the app-controlled LEGO Technic category.

In conclusion, the LEGO Technic App-Controlled Transformation Vehicle is an appealing set for building enthusiasts, particularly given its imminent retirement and potential for purchase at a discount. However, it is advisable to approach this set with caution as an investment. Despite belonging to a solid theme, its unspectacular performance, coupled with consistent and prolonged discounts, raises concerns about its post-retirement value. The cautionary tale of the closest direct comparator, the App-Controlled Top Gear Rally Car, which experienced negative growth post-retirement, further emphasizes the need for potential investors to exercise prudence and consider alternative options for more reliable returns in the LEGO Technic market.
