Lego has started out as a wooden toy company in 1936 and is now the worlds best selling toy company with toy bricks. I recommend for 2015 Lego speed champions the Lego Mclaren P1 or the Lego Ferrari Laferrari and for 2016 the Ford Mustang and Chevrolet Corvette Z06.
I have seen great reviews online and on YouTube think that these sets are good because I have the La Ferrari and it’s pretty good. Until it was destroyed by someone. On the back of each box it tells facts about the car and shows a picture of the real car on the back. I wonder if Lego will use Koenigsegg or Bugatti but they have done this in the past with Lego Racers and in that series they have created the Lamborghini Gallardo.
They have many more in the racers series like monster trucks and Formula 1 but Speed Champions is the one to go for. But you should subscribe to JANGBRICKS they will tell you all about every single detail of the car , and the mini-figures,and everything that comes with it.
At brick vault YouTube channel they tell you all 2016 Lego sets
