It is the second set of the carrera go series that I buy with the purpose of connecting it to the first one and having a bigger track. Compared to the first one, which had two F1 racing vehicles, I noticed two negatives. The first one is that in the "dirt" part of the track, the vehicles often get stuck, and the second one is that the two vehicles are very light and high, resulting in them constantly coming off the tracks. Overall, the vehicles look very fake compared to F1 vehicles. If I didn't have the vehicles and the experience from the previous set, I think I would have a very bad impression of Carrera tracks. Now, I'm not too bothered, I race with the old cars...
