"Ok, this will be a long one. The Lego Lamborghini Sian is one of the best sets I have ever purchased and built, It is a masterpiece of mechanical engineering, and all the features work extremely well. The Scissor doors have got to be a highlight, they are smooth and it is easy to access the lever for them, the spoiler looks impressive, and is also easy to activate. You also can't help but admire the workings of the gearbox and engine. The steering is also a nice touch. Yes, there are some...mishaps, like some people have mentioned with the '50 shades of green', however, my set only had about 4 or 5 shades, and when looking at others photos compared to my car, LEGO is definitely improving their quality control on this set. The interior is not quite as good as the Bugatti, being a similar colour to the car itself, however, when you realise that all the pieces are printed, when you see the Italien flags in the back, that your one will be unique to you, and that it just looks so good, you just have to love it for what it is, a master of engineering and exterior design that normal people like us could probably never think of designing. That being said, the Bugatti Chiron will retire sooner, so get that before if you don't already have it, as you will have at least another two years to get this one, that being said, the lamborghini looks better, especially around the front, and has working suspension which doesn't require additional fixing, and if your looking at the pictures and aren't sure, remember to look at the pictures in a real life context, as the model will look so much better than on a all black or all white background, pictures don't do it justice. Remember, when you buy this set, you don't just get a LEGO set, you get the unboxing, (Truly spectacular), the exclusive owners club content, and the knowledge gifted to you as you start and work through the instruction books. I would definitely recommend this to anyone who is looking for something challenging, or to do with friends or family, and has the money to do so. I have the cancelled holiday to thank for that one."
