I just started that, played the first 3 chapters. It’s nice having a bit of a Top Gear homage added to the game. All it needs for the Bowler challenge is Hammond yelling “I am a driving god!”
The new Horizon Story chapters in FH4 are fun. It's Top Gear inspired and features all British cars. I also found it the easiest to 3 star, coming up with 29/30 without much effort (rewinds ect). So now you have a new way to earn those 100 stars and Complete 40 chapters achievements easier.
