“The McLaren Senna GTR is billed as a game-changing track car, clocking in the fastest lap times outside of Formula One. It’s an utter powerhouse of a machine. At only 12 inches of length, 42123 McLaren Senna GTR will have its work cut out to do the real automotive icon... More justice.”

The Brothers Brick
“All in all, the new LEGO Technic 42123 McLaren Senna GTR, by all means, is nowhere near the perfect LEGO Technic vehicle of the scale. It has a bunch of drawbacks, although most of them don’t make it less playable or less displayable. What is important is that the new... More McLaren Senna shows amazing improvement over 42093 Chevrolet Corvette ZR1, which belongs to the same category of models. And most of the improvements promise the theme’s very bright future.”
