    Epic model, grandson gives it "10 Stars"

    What an epic Lego Technic model car this is! My 8 year old grandson was blown away with it - he kept talking about and looking at and being amazed over it all afternoon. He said it's the best Lego item he has or will ever have. I am saving the instruction booklet (naturally) and also the box. This may get him interested in other Technic sets, perhaps motivate him to develop the focus and patience to assemble them himself (this came fully built). He likes putting Legos together but doesn't last long at it (yet). He noticed numerous unique and interesting features and functions and is eager to find, among the dozens of minifigures he has, just the right guy to put inside as the driver. I've not seem him this excited about a Lego item in a long time.

    Great kit!

    Honestly, great set. Love the attention to detail with a crankshaft the actually actuates the pistons. The active steering via the top gear is very smart. time spent was worth the build. Intricate but satisfying. It will live on my shelf for years to come.

    Great alternate builds on rebrickable

    I have 2 of these kits. The Senna build is real nice, but my instruction book got damaged so I ordered a 2nd kit. Rebrickable has great alternate builds including an F-1 car. There are other builds too. It’s a very versatile kit for the price.
