Is LEGO MT-31 Trike a good investment?
MT-31 Trike currently trades 822.0% above its $10 retail price, and it is retired, so no new supply is entering the market. Past performance is not a prediction — condition, packaging and how long you hold all affect what a set actually sells for. BrickStats reports the numbers rather than giving investment advice.
Why is LEGO MT-31 Trike so expensive?
MT-31 Trike was released in 2007 and has since retired. Once LEGO stops producing a set, the only supply is what is already in circulation, so sealed copies in good condition compete for a shrinking pool of stock. That scarcity, not the parts, is what moves the price.
