How does set completion work?

Each set you own shows a completion count — like "4 of 6" — meaning how many of the set's member models you currently have attached to that copy.

How it's counted

The catalog Set defines the full member list. Your owned copy counts the pieces you actually have linked to it. If a set is supposed to contain six cars and you have four, you'll see 4 of 6 and which ones are missing.

If the same car appears in the box multiple times, completion counts each expected instance — see Why is the same car listed multiple times in a set?

Filling the gaps

• Got the missing cars but they aren't linked? See How do I add the missing pieces to a set?
• Logged them separately earlier? See What are "loose pieces" and how do I promote them into a set?
