Very nice set. I see a lot of people saying that the instructions are unclear or even contains mistakes, however I found none, and the instructions are easy to follow. I did however manage to turn the rear diff 180 degrees making the car unable to roll! But That was my own fault. Only reason I'm not dishing out 5 stars, is because of the slight colour difference in some of the green bricks. I would expect a perfect colour match in a set as expensive as this.
