Good fun build….. have to think about this one!

I enjoyed this build, no two cars are every constructed the same which means you have to concentrate to get an accurate build. That's all part of the fun here. I would have like to be open the back of the car so the engine is more visible, Stickers were excellent on this set….

Start Your Engines!!!

This my 1st time buying a Lego Technic car. Fan of sports cars, Formula 1 , Indy, Nascar etc. This McLaren caught my eye. For the size and price it was worth it. It was a bit of challenge to build. But worth it. The only thing I do wish is the wing in the back that says GTR was able to tilt up ever so slightly, so it shows the GTR letters at the back. But other than that. I'm a proud owner. Keep up the good work Lego! And make more of these mid size affordable race cars!! Vroom Vroom !

A pretty cool car and fun to build

This was my first time building a car at this scale and had a lot of fun assembling it. It's not as functional as the larger cars such as steering wheel is just for show and only one wheel is connected to the engine and has a different colour LEGO part in the middle of the rear wheel for some reason. But overall it's a pretty cool car.
