⏳ Active
The Challenger Set 400 with Motor has moderate investment potential due to its age and classic nature. While not a highly sought-after set, its completeness, condition, and working motor will impact its value. As a vintage set, it appeals to collectors interested in early LEGO designs. However, the set's relatively low piece count and lack of exclusive elements might limit significant price appreciation. Keeping the set sealed or in excellent condition is crucial for maximizing its investment value.
