I bought the car for my son for his birthday. He has a lot of practice in terms of Lego Technic and has the car as a 9 year old perfectly able to build their own. Of course, the construction takes a little, the result compensated but then every effort! The model is simply designed class. The car can be steered and means gears can mechanically open the hood (rear) and the storage space up front. The pistons of the engine move while driving, my son and I are thrilled. Delivery by Amazon as always super. Ordered, the next day was the package already there!
