Bought this for my 7 (nearly 8) year old nephew for Christmas as we both love the TV show.
We have had moderate fun playing this but the questions are far too nerdy for a child, unless they have watched every single episode of Top Gear several times on Dave!
I can't see him asking to play this again as he got bored pretty quickly with it (unlike the other board games we play)
As far adults, there isn't enough depth to the game to hold your attention very long.
For £20+ I would spend your money elswhere - you'd be better off with a game that encouraged skills other than watching lots of episodes of Top Gear (for kids) and as there isn't enough intellectually in this for adults.
