Tricky for age group but looks great made up
Great car, definitely needs to be 10+ lots of small fidley bits that need small fingers. Some adult help need for instructions but looks amazing when complete.

Great if you love a challenge.
Bought for Christmas for my son, first time ever building technics, always had normal Lego previous.Lots of small pieces to contend with, the book doesn’t really give clear concise instructions so a bit of guess work involved. Took a while to build, after making one or two mistakes, son got a bit frustrated first time round, but we got there in the end. Great once built though, looks great! 🙂👍🏻

Very good present
I recently gifted my 11-year-old son the LEGO 42123 Technic McLaren Senna GTR Racing Collectable, and he loves it as an avid LEGO enthusiast, he was over the moon with this kit.This LEGO model is quite challenging for an 11-year-old. However, I was impressed to see how he managed to put it all together. It's a great way to challenge his building and problem-solving skills while having fun.The attention to detail in this McLaren Senna GTR replica is remarkable. It's not just a toy; it's a mini engineering marvel.Overall, this LEGO set has been a big hot. It's an ideal gift for any LEGO-loving child who enjoys a bit of a building challenge. I'm glad I chose it as a birthday present for my son.

Great build but pieces missing
I thought I'd try something new and start relatively easy. Enjoy it right up to the last 10 minutes when I found I had 2 pieces missing.I can guarantee they wasn't dropped or lost as I opened each packet into a plastic container.I feel really disappointed and now have to buy the 2 missing bits at a cost of £5.00 (best price I can find).With this problem I can't honestly give it 5 stars.

Adult gift.
Gift for an adult who enjoys Lego more now than when he was younger. Ideal for anyone who enjoyed both Lego and F1 racing.
