Really liked the completed look and was fun to build. If you enjoy the shorter build times this a great one to go with

This set was a fun build but was very challenging for an adult.  But for the money it was a great deal

they are easy to build expt if you lose the parts

[This review was collected as part of a promotion.] I'm 79 years old and like to work puzzles and Lego Model Cars. Just something to keep my hands busy and food for the brain. Also, just something I enjoy doing.

Brain Food

nice car

This lego was way bigger than I thought it would be, we haven't opened it yet as it's a Christmas gift but I know that my 12 year old is going to love it.  We got this on a Black Friday sale for $25 and I came definitely say that this was a huge deal.

Love this Lego.

This was a great build. With a lot of stickers if you like that. The colors are great. And the engine really turns for you to see how it works. The instructions are easy to follow like lego usually are however if you have difficulty you can also you the interactive Instruction online to help out. Overall this was a very fun build and another lego for my collection.

Great build and play features and great value.

My son loved this I was very impressed as how fast he put it together.

Excellent

[This review was collected as part of a promotion.] Exceeded my expectations, especially during the rush of the holiday season.

False advertisement. This is not a legitimate Lego set as it shows in the image. This is a Chinese replica. The building instructions aren't close to be legitimate as front and back covers are black. Bags in the sent aren't numbered so you will need to go through ever bag to find the piece you need.

False advertisement. Not a legit Lego Technic set

LEGO Technic McLaren Senna GTR 42123 model toy building kit featuring a blue and black race car with authentic McLaren graphics, opening dihedral doors, and a visible V8 engine with moving pistons, displayed with its box showing the assembled model in motion, suitable for motorsport fans and collectors.
