"The details include moving pistons, an operating differential, steering, and a working suspension." $180 for 1400+ lego piece car, over 25inches long. Cool product, but I always feel legos don't capture the right details. Obviously can't get them all, but the ones they chose always leave me wanting more. still a great product for the price and the interactivity! https://www.mclarenchat.com/forum/news/1893
