## Questions & Answers

**Q: Where is it made?**
A: Hi there! Our sets aren't made in any one place. Instead they're often made up of parts that come from all around the globe. Any single LEGO® set might have parts that were made in our facilities in Denmark, Hungary, Mexico, China, and the Czech Republic. So your set's kind of like a little trip around the world all in one box! - Emily, LEGO® Customer Service

**Q: Is this a good Legos for an 8 yrs. old boy?**
A: This is perfect for an 8 year old boy. My son who is 7 had little difficulty putting it together. It is a very fun toy for him to play with and experiment in regards to building.

**Q: can this car fit a lego human in the seat?**
A: Hi there! While minifig might be able to squeeze in, they'll likely need to have their arms raised to fit, which will look a bit odd! - Emily, LEGO® Customer Service

**Q: Why does Amazon ship Legos in a flat envelope and crush the box during shipping? Why is there nowhere to report your crappy packaging anymore?**
A: Hi there, 
We're sorry for the frustration. In cases like this, it is best to reach out to the seller directly to report the issue. Just find the set in your Amazon order history and select "Return or exchange" to get started.
