10/10
That said it wasnt all perfect, I do wish they had simply gotten a large part of the Blue Ridge Pass blocked off to go as fast as they want, as they often do other times (but we don't see) but the turn of events that followed created for what i thought were some genuinely classic Top Gear moments.
on the Stig stuff: I wish I could be certain how much of that stuff was light hearted fun and how much of that was as honestly brutal as it could have been, regardless it had me cracked up the whole time and "emergency stig" at the end provided a crucial final laugh, true props to Ted Needell for coming in and TG themselves for getting him, its clear any bad blood they talk about having with 5th Gear is only in good fun, and its always nice to see old friends helping out a friend in need.
On a final note, I am truly excited for the season to come from the preview. I love that they seem to be pulling a 'Mythbusters' by having a car falling from the sky racing a car on the ground, and if the show is even so much as name dropped (doubtful, though it is) on TG i will be ecstatic. Also, the Aussie challenge looks amazing, I'm assuming its vs. Top Gear Australia, which could definitely produce some great laughs, but it makes me more excited for the future prospect of TGUK getting with TG america for some challenges (now that i think about it, this UK episode did draw some similarities with the moonshine cheap car challenge from TGA)
