An absolute deal for the piece count!
For the amount of pieces in this set this one is an absolute deal! It all went together well, instructions were easy to follow, and no missing pieces. Getting back into Legos now that my son is into them brings me back to when I was a young kid in the early 90s obsessed with these things. They really have come a long way and are a blast to build now as an adult! This kit took about 4 hours to complete and has moving engine pistone when you drive it which is just so cool to see! This kit is a must have for the price point and piece count for your collection. I attached a picture to show other vehicle in the current fleet for size comparison. Ranging from 100 pieces for the small blue car to over 1000 on the dark green one. So you can see if you are looking to know how big each of them are based on piece count and price.

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!

Experience required
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!

Excellent passe temps, encore quelques heures pour le finir cette voiture qui est magnifique. Très content de mon achat. En rachètera sûrement une autre.

Carro bem esculpido usando técnicas de construção interessantes, bonito e bem detalhado. Como doador de peças é relativamente medíocre, tendo poucas engrenagens e algumas peças raras e incomuns, como os painéis pequenos. Falta um diferencial, mas provavelmente foi um sacrifício em prol da estética do modelo. Muitos adesivos, mas que contribuem muito pra que o modelo tenha todo o impacto visual que pode ter.
