LEGO Technic Lamborghini Sián FKP 37 42115 Building Set

[This review was collected as part of a promotion.] A wonderful add to my collection of these classic pieces

Biggest build yet, a step up from g-wagon. The build was interesting, and i would describe the first couple of boxes as quite painful (engine & gearbox) - very fiddly, but i suppose that should be no surprise really. The rest was more straightforward. There were odd places in the instructions where the connections weren't as clear as you might like but in the end I didn't make any mistakes - the best example i could give is when the wing doors are first connected, it just seems wrong but once you follow the next 3/4 steps it makes sense. Also, i built from the digital instructions in order to keep the booklets in good condition - I did get the long, flexible green things in wrong place (there are 2 lengths). Each box (1-5, 6 only contains the wheels) has 8-10 bags in it and i spent a lot of time searching for the pieces in the various bags. it's a game of patience, you can't get frustrated. Overall i'm estimating about 15 hrs of actual build time. The model i have was originally purchased in 2020 but was still sealed, it does have the colour variations that many comment on (some pieces specifically seem to be susceptible), however it doesn't actually look too bad on the finished product. Whilst it's an impressive model, it's not as stunning as I expected. Overall it's good, but not brilliant.

This was a challenging build, difficult in parts but the end product looks fantastic. Colour is striking, gold ’alloys’ really finish it off, the attention to detail is great. Makes for an excellent display piece. Highly recommended if you enjoy a challenging build. I hotted mine up with a light kit.

my favorite feacher are the doors and the gear boxs

Loved building this model finished it within a week but can't seem to get on the owners only page to register the serial number

I had a bunch of fun building this set and I would recomend this to anyone who likes the expierence of building difficult builds.

My 2nd of these big detailed builds and I loved it! Of all my autos, it’s one of my favorite builds

As soon as I drove this model just a few time's times one of differential gears fell out. It was very disappointing. I cannot play with this model. I can only put it on display. I think the whole reason for these technic cars is the playability. The doors are amazing how they work. It was a good build overall but the differential gear fell out and it’s very hard to get one back in due to all the gears covering up the differential the Bugatti you could put the differential gear back in easily maybe you should have the differential gear more accessible.

Incredible product. Instead of a normal LEGO building kit this was an luxurious Lamborghini experience brought into home. The box design was fantastic and so were the instructions. The small stories and facts were a nice add-on that differs from the other sets. The overall look is very good and the functionalities are great. The spoiler contains some disrupted colored parts but for me that was not really an issue. I like the lime color. The steering wheel turns a bit stiff because of the weight of this gigantic Technic build. So it is not very playable but astonishing for display. For me the most mind-blowing functionality was that the shifting flippers behind the steering wheel really work!

Bought for my 15 year son, he has a large selection of technic sets but this was the most challenging yet. He completed in around 20 hours and loved building it. The detail is unbelievable and the finished model looks amazing.

Got this for my wife, she finished it within a week / about 1-2 hours everyday . she loves it , thank you Lego for making another outstanding set.

It looks pretty accurate when done but,I experienced many problems while building such as missing pieces. I counted and found that 8 times that the piece I needed was not there. The photo shared is pieces from bag five(not all the pieces are there because it was taken during the building process) but there is piece 4211805 missing.

This set was super fun to build! It took 2 and a half weeks and every second was worth it! The build itself was enjoyable and rather easy except certain parts. The instructions were mostly clear. The size surprised me for sure. The green is also perfect. I can't help but stare at it. Excellent set!

Builds well, functions perfectly, the visible gearbox and raisable spoiler are an awesome touch. I've rebuilt mine several times and I have the callouses to prove it. Y-headlights and low fast design are my favorite part, although I wonder how it would look if the rims were a dark silver instead of gold...

I’ve been a Lego enthusiast since I was a kid. Now having my own kid who is obsessed with legos has rekindled my own love. My wife gifted me my first technic set (Porsche 911 RSR) for my birthday. I loved that set. I them came across the Technic Lamborghini Sián which I knew I had to get. After just finishing the build I have to say that it is one of my all time favorite Lego sets other than the Creator expert Apollo 11 lunar lander. The build itself is quite challenging and requires a lot of attention to detail as the instructions can at times be tricky. The final product looks amazing and a very true Lego representation of the real masterpiece. The functionality of the gear box is amazing and a true testament to the ingenuity of the LEGO team engineering. I read various reviews online about color mismatch which must have been remedied as every green piece had perfect color match. My son has loved playing with it as I have myself. As a parent I also feel that the Lego technic sets really entices a child’s mind and intellectual curiosity. Overall this was a fabulous set which I am happy to have been able to get before it is retired. I highly recommend it.

This is a really wonderful product, unbelievable how it was designed

This Lambo is beautiful! The neon green absolutely POPS. The technic build is very well thought out - challenging but still a lot of fun to build. I have it displayed on a beautiful acrylic stand and it looks awesome!

Initial build - "this is pretty cool" Post 42143 Ferrai Daytona SP3 build - "this is average at most" The way the car came together is quite boring and the key elements like the door, lights, rear diffuser is unforgettable at best. Whilst building the Daytona, I kept asking myself "did the Lamborghini have this element?" or "what did they do for the lamborghini for this part?". This build was very forgettable. I bought the daytona straight after i finished the Sian, it's only been a couple of days between build and yet, I don't remember much of the Sian build.

[This review was collected as part of a promotion.] Unique product, I am very satisfied. I embarked on an incredible adventure. I recommend it.

This is a very hard to find Lego. Get it while you can. Great Lego set 10 out of 10 would recommend.
