"I'm a big Lego Technic fan and have grown up building and enjoying increasingly expensive and complex kits.
I was bought this for my birthday and at first was very pleased, but as my 2 hour build time suggests this kit isn't very complex at all, visually apparent when scanning the parts bags by the severe lack of gears, springs, pneumatics or any of the cool stuff that makes the more expensive builds generally more fun and challenging.
What you get instead is a Bluetooth controller module and motors which are very impressive, but make you quickly realise is where all the cost is for this kit (along with the Top Gear branding), as the parts list is really quite basic.
