  1. Thoroughly enjoyed making this car. It is sufficiently demanding to make it a worthwhile task. I went wrong a couple of times, which meant a bit of dismantling. However, got there in the end and it makes a great display model. Difficulty is keeping young probing fingers away. Highly recommended and a saving on price at Amazon. 
  2. This was bought for a birthday present from my 7yo son to his Daddy for them to do together, but my son ended up doing it all himself - he absolutely loved it! He loves Lego Technics builds and did this one in 3/4 sittings, even getting up early before school to do it, he enjoyed it so much. Some technics kits are very expensive so this was great value for money and my son loved doing it and now plays with the finished product.  
  3. Had received a gift voucher and then gave it to me. Although I'm totally the Ferrari fan, I like the Senna very much, in real and in Lego. Lego is not so good when it comes to sports cars (Ferrari 488 absolute catastrophe) but the Senna is really clear. Optics are good as well as the functions, only the rims are too small for me. Lego should really add. Other manufacturers of building blocks are now doing this around worlds better, and they are just as good in quality. In some cases even better and cheaper.
