Retailer reviews

Unable to communicate normally via the chat box. I have not received anything twice through bol.com. This was likely my last order through bol.com.
My 10-year-old son has enjoyed playing with this LEGO set twice, as he made a building mistake the first time. The finished model is now on his desk.
My grandson turned 8 and loves playing with LEGO! When he opened it on his birthday, he immediately said: "10+!!" He was very happy and started building it right away. I thought the pieces were a bit too small and I thought: "Hopefully it will work!" The next day, we received an app where he proudly showed off the car! And we were also proud because he was able to build the "10+" LEGO set.
I was late because I was building it.
This LEGO set is definitely recommended. It looks great and it's a challenge to build.
Beautiful model. It will look great in my collection. However, there was one missing piece, luckily it wasn't essential for the complete build and I could probably find it somewhere in my box of spare pieces. But it did cause a bit of frustration while searching haha.
