I always was impressed by the bodywork complexity on the modern F1 cars and how the wings and body flow together. I liked this kit because it did a good job at representing the F1 cars for it's size. The only thing I didn't like about this kit was the fact that the whole rear end was taken up by this huge, ugly pull back flywheel motor. This problem was solved by taking this out and replacing it with bricks that flowed more with the rest of the body. I also added the rear light that signals when the car is under it's pit road limiter. I am happy with the end result and think that it is way better designed than Lego's version.
