Our biggest little Lego fan usually prefers the movie or other themed sets, but most of all, he loves to build sets that spark excitement and challenge. The building sets that interest him the most, he completes in one day, usually the same day he gets it. I feel the same way about a good book as he does his favorite Legos, he doesn't want to stop and put it down! He built this TECHNIC set one evening with lots of excitement and enthusiasm. The LEGO Technic McLaren Senna GTR 42123 model building kit is packed with realistic details. This supercar toy model’s authentic features, like the detailed V8, had him running excitedly,to show us the moving pistons. Later, he was also enthusiastic about the dihedral doors that open ‘up and out' in the unmistakable style of the real McLaren. So many cool features like steering the McLaren toy car using the wheel on top. He did mention a few times that the build was hurting his fingers a bit, but said, "it's worth it"! This 830 piece set would be a great gift for any motorsport, supercar, or Lego building fan. We added a few more shelves above the Lego crafting table to display this completed remarkable car. The finished model measures over 3 in. (9 cm) high, 12 in. (32 cm) long and 4 in. (12 cm) wide. This collectible McLaren toy car features eye-catching graphics and colors. I recommend it for any Lego fans, aged 10 and up, who are ready for a new challenge in advanced building toys.

My 12 yr old has just put this amazing LEGO Technic McLaren Senna GTR together. The finished product looks exactly like it shows on the box and in the website! It's larger than we expected which was a pleasant surprise! This car is just slick looking and very detailed. Perhaps the feature that sets it apart from other sets is the pistons that move up and down as the car drives! Also the wheels can turn aided with the use of a knob of top of the car. The instructions were clear and precise. There was minor confusion putting it together, as there were multiple bags labeled for each of the steps. But he was able to figure it out easily. Overall it took about one and a half to two hours to build. He was blown away with the finish product! Absolutely recommend this!

I step away from legos when I finish Highschool, and growing up I was always intrigued by Lego Technic builds but never owned one. This was my first ever technic build & the nostalgic memories and excitement of building legos came right back, like it never left. The Senna is an excellent purchase especially for starters who have patience, some tricky parts but nothing that you can’t overcome. This build is worth every penny, I really enjoyed my time building it. I know I could’ve finish it in like a day or so, but I savored every moment, just put some music on an rock out. To make it even easier for it being my first technic build, I just did bag number by bag number instead of dumping everything out the bag. Also the most exciting part of this build is putting together the engine then connecting it to the chassis, then seeing the rear wheel drivetrain move the pistons(So Cool!). I will be purchasing the 911 as well,so I suggest that you do the same. Thank you Lego, the Senna is a must have!!.
