Super car racetrack from the leader

Ordered for my boy (12 years old) Christmas Racecourse. Once he saw her lying under the Christmas tree, was no stopping and we had to also build the same. The initial difficulties in building were due to the lack of experience on my part and the peripheral equipment of the train. When she finally stood, the first impression was very tidy. Now, after nearly two weeks in intensive use, I can only say that the expectations were fully met, which means my son is hard to separate from the web. Disillusionment was however broadly when I had pulled the extension of railway into consideration and in specialist shops would buy more some parts. For this purpose was only noticed that the customer should specify perhaps two pieces of track from Amazon itself as a race car in replacement costs almost as much as the whole train ?! Otherwise full purchase recommendation.
