"I received this set last December, and assembled it immediately. It was not too hard to build, and I finished it in less than six hours. It is fun to play with, and easy to customize, and installation of the power functions motor parts is simple and relatively straightforward. The car suspension is good, (quad spring shocks) and the car has very pleasing aesthetics. I would recommend this set to any advanced LEGO fan happily. It's a little pricey, but certainly less than some other technic sets. Overall, it's a great buy!"
