I have built several technic cars where the trunk (boot) raises and the roof retracts but this is one of the best versions of these cars. I went with the super dynamic model that had all the power functions. Instructions were excellent as well as the cable management. Accessing the batteries were easy. I also customized this model with the BriksMax Lamborghini Sian sound and light kit. What was great was the space under the hood (bonnet) had plenty of room for the light kit as well as the battery pack, so both are hidden very well. Parts fit was great and I appreciate models that come in bold colors. Guly is closing in on the Lego brand.
