    Good build for beginners and experts

    This was my first technic build ever and I couldn’t wait to make my favorite car. The build was easy to understand with minimal problems building, the build was fun and challenging to keep me going on until the product was finished. Once it was finished I was surprised just how detailed and accurate this was to the actual car especially for the price (which is way cheaper than it should be) I really couldn’t complain at all. The build was fun and challenging but not too stressful and boring. I would recommend this build to beginners and experts of lego technic

    First off, I am so disappointed that Lego didn't go with this model for the 1:8 Scale Technic release. When I first saw the teaser images from Lego I was absolutely in love with this model and then when I found out it was roughly 1:16 I was disappointed. It is so beautiful that it would make a fabulous addition to the larger builds. There are a few pre-printed pieces in the set but a large portion of the decoration is by stickers. Yep, sticker heavy but well worth persevering with as they elevate the look immeasurably. The problem with the smaller Technic builds, for me, is that the engine block is simplified right down and that is my favourite bit of any Technic build. Have to say I had a complete blast building this car and enjoyed every single second of it (you couldn't wipe the grin off my face as it grew into a beautiful vehicle from chunks of plastic).

    I found this easy to build. My only differing opinion to the instructions is the tail fin should be up the other way with the GTR stickers on top. It looks better that way to me.

    This my 1st time buying a Lego Technic car. Fan of sports cars, Formula 1 , Indy, Nascar etc. This McLaren caught my eye. For the size and price it was worth it. It was a bit of challenge to build. But worth it. The only thing I do wish is the wing in the back that says GTR was able to tilt up ever so slightly, so it shows the GTR letters at the back. But other than that. I'm a proud owner. Keep up the good work Lego! And make more of these mid size affordable race cars!! Vroom Vroom !
