  • Fantastic Build!
We have all the cars in this series, and each have been fun and impressive builds. Good price point, surprisingly durable cars once assembled thanks to the Technic components, and display well. I love how Lego consistently stays relevant and interesting as my children grow. Kids gain motor skills, patience, problem solving and appreciate the complexities of making the car wheels turn from a steering mechanism. WAY better than video games. ... show more

  • 11Yr Old Grand-Son Loved It!
Purchased for our grand-son who put it together straight away. It was add to his wall collect the same day, quality product with easy to follow instructions.

  • Absolutely amazing for adults!
This was bought for a 28 year old for graduation and let me tell you it is quite enjoyable even for adults. The detail is amazing! There is so much quality in the design and focus to the point of making an engine! This is adequate value seeing as lego is always expensive. I'd recommend this for adults based on the focus and difficulty! ... show more

  • SO COOL!
My son got this as gift. The detail of the design and stickers are very cool. If you have a child who loves to make or create things, this is a great gift. I do believe it was worth its money. I bought another one for him, as well, because he now displays it for people to see!

  • Great addition to your collection not just for kids but adults too
It was fun making this build. It was very reasonable. It has an opening door and front wheels can steer.

  • Great value for the money
I bought this for my teenage son who still loves legos. It took him a bit longer to put together but he was happy with that. The car is very cool and he displays it on a shelf. Great gift for kids and those young at heart.

  • Experience required
The media could not be loaded. Quality, design, are both 10 out of 10. But! If this is your first time, age does not matter, it will take you at least four hours to put together. If you are buying this for a 10 year old, as the box suggest, it will still be difficult for them, as it was for me and I’m 27. But, like I said, this was my first time. I still had fun, putting it together, and it is bigger than I thought it would be. Because all of the promotional material and the pictures in the reviews, made it look smaller than it is, once built. Great bargain for the price, they could easily ask $80+ and it’d still be worth the purchase. The ONLY reason why I did not rate this a 5/5 stars is because of the learning curve. The more experienced you are, the shorter the build time. Even if this is your first time playing with Legos, I believe anyone can put this together. Although, if they are under 10, then parental assistance may be necessary. Great for S.T.E.M. children! ... show more
