I wanted to like this set more, but there are several areas where the instructions have steps that are impossible because the parts don't have room to connect all the way. There are also a lot more replacement pieces than what's advertised. Some are fine, but overall this leads to a much more fragile build (more fragile than what it would be with all the proper pieces). The windshield and roof is the biggest issue here, where the roof doesn't have enough pieces to hold it together properly, and the windshield pieces are completely different with studs on the outside, and with a full plate thickness, so you can't angle them back properly. The front of the fenders are also held on by only one stud, so they fall off easily.
Additionally, with the roof on, you can't really fit minifigs in there

I’m extremely pleased with the brick model “ Spirit of Nemo”. The Joy brick components were well packaged and are very durable. All building components fit precisely in place creating a highly accurate and detailed vehicle. The completed Spirit of Nemo looks awesome! A very clever design. I was quite impressed with the clear and easy to follow instruction manual. Thank you Joy Bricks for an enjoyable and great building project.
