The LEGO Technic line is notable for the scale model size and the attention to detail in every build. Assembling a car is a way for growing kids to expand their LEGO building into moving parts and satisfy their curiosity about what is under the hood. The Huracán has a realistic-looking V10 engine and the lime green color will make this stand out on a shelf.

As a collector, this delivery truck has been on my wish list for ages. I love that it’s not only the big rig in bright LEGO yellow, but also that there are little boxes that look just like tiny LEGO sets. It’s the perfect addition to any LEGO city, or for kids who love playing with trucks.

If they’re constantly building, this remix set is a way for them to come up with endless creations. This set comes with the pieces they’ll need to create a helicopter, fire truck, and submarine.
