nice big car ,strongly build, it was fun to put together, kids will love to play with .looks good with my other six big lego cars pull back and watch them go across the room. the price is right for this size car. looks good on my shelf with the other ones.

### ⭐⭐⭐⭐⭐ An absolute deal for the piece count!
*by K***S on March 15, 2023*

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.
