Featuring the W16 engine, the most sophisticated engine from the Lego world, the set lets you assemble the parts like an automotive engineer from Bugatti Automobiles S.A.S.

Highlights:In the luxurious box you will receive a coffee table collector's booklet for comprehensive building instructions. The signature blue duotone color scheme is made even more eye-catching with the unique decal set.

  • Online content can be accessed by following the serial number engraved under the rear bonnet and if you open the bonnet you will also find a compact storage space with a Bugatti overnight bag.
  • While the engine features moving pistons, the cockpit features a moving paddle shifter for the eight-speed gearbox. Opening doors give access to the detailed console and moving steering wheel.
  • Reach top speed by inserting the top speed key and swapping the active rear wing from the detailed glossy aerodynamic body. Stylish disc brakes for low profile tires and wire wheels with Bugatti badge will catch your attention.

Light kit:ThatLego Lighterfor different areas such as wheels, taillights, headlights, interior lights, etc. can be turned on/off individually or together with the remote control. It also has buttons to reset effects, change brightness, add sound and select X1 or X2 to keep the light always on or in blinking mode respectively. There are five warm white strips, 30cm slow flashing red and white lights and two 30cm white LEDs. The Briksmax lighting set includes seven random Lego bricks, three 15cm and two 5cm connector cables, a 6-port CR2032 oval expansion board with AA battery boxes, an adhesive square and a 30cm power cable.

4. Tower Bridge 10214

The Lego Creator Expert model has 4295 pieces and is suitable for ages 16+. The Tower Bridge 10214 set perfectly depicts the original architectural summary of London. To build the miniature set of the world-famous structure, you must add the suspensions by fitting tiny pieces together, and the towers on top of each bastion require skill to be attached correctly so that the height of both bastions remains the same. This timeless London landmark on the River Thames has enchanted locals and tourists alike since 1894 - it takes advanced building techniques to recreate its magic.

Highlights:The most complicated part of the set is the functional drawbridge, which can be opened like the original Tower Bridge to let cargo ships pass. Several rare parts and bricks in rare colors are added in this model, which may make you feel unfamiliar with the building process if you don't follow the building instructions.

  • Featuring four miniature vehicles, namely the red London double-decker bus, the green car, the yellow truck and the black cab, the bridge takes you back to the streets of London but requires skill to ensure the bridge remains stable.
  • The paired towers are connected by the opening drawbridge and the connecting overhead bridge. If you don't assemble the pieces correctly, the towers and bridge could wobble and crumble.
  • Lock the different sectors together to keep the structure upright, and during washing or moving the sections can be taken apart. Beige bricks look too similar and distinguishing them will be a tricky task to create the hanging pieces and construct multiple layers.

Light kit:ThatLego lighting sets contain twenty warm white tinted strip lights along with the three blue strips. Whilst the white LEDs highlight the top port, inner compartments of the bastions and towers, suspensions and drawbridge, the blue LEDs enhance the base to represent the River Thames. ThatBriksmax Tower Bridge lighting setalso includes seven 30cm, four 5cm and eighteen 15cm jumper wires, four 6-port expansion boards, adhesive square, AA battery holder and 30cm USB power cord.

3. Fire Department Headquarters 75827

Suitable for ages 16+, the Lego Ghostbusters Firehouse Headquarters 75827 has a simple look, measuring 14" tall, 9" wide and 14" deep. However, assembling the 4634 pieces will be a time-consuming task, especially when the walls can be opened up to stretch the model up to eighteen inches wide. The hinge that ensures the opening function does not work if there is a small problem in the construction of the outside. Die-hard Ghostbusters fans will love the challenge of creating the detailed rooms filled with ghouls like the Library Ghost, Zombie Driver, Blue Ghost, Pink Ghost and Slimer.

Highlights:You'll need to memorize scenes from the movies as you role-play and place the nine minifigures of Peter Venkman, Winston Zeddemore, Janine Melnitz, Egon Spengler, Raymond Stanz, Louis Tully and Dana Barrett, and you'll love the decorative Ghostbusters arms.

  • Seven landing legs, lower and upper quad laser cannons, detachable canopy, cockpit, lowering boarding ramp and detailed hull panels make building the exterior complicated but fun.
  • The Dejarik holographic game, seating area, remote control training combat helmet, rotating seat, engineering station, and decorated main cargo hold passageway require extreme skill.
  • Building the hyperdrive, console, engine room, two doors, underfloor storage, two escape pod doors, access ladder and engineering console will take some time.
