Buying second-hand LEGO can be fantastic. Sets that cost hundreds of euros at retail, you sometimes find on Marktplaats or Vinted for half the price or less. But I've also paid for sets that turned out to be incomplete, or where important parts were missing. Here are the 10 things I now always watch for.
1. Always ask for the set number
If the seller doesn't mention the set number, ask. With that number you can look up which set it is exactly, how many parts it should have, when it was released, and what a fair price is.
2. Check if the set is complete
Here's the most underestimated tip: ask for proof of completeness. Is the manual included? Original box? Someone who really has the set complete usually has no problem sharing photos.
3. Original box = more value
A set with the original box in good condition is significantly more valuable than a set without box.
4. Watch the minifigures
Minifigures are often the most valuable part of a set. Ask specifically which minifigures are included and whether they're complete.
