So I've seen it now, and I'm afraid the Norway bit - apart from some nice scenery - was suffering from a bad case of GrandTouritis... pointlessly stupid cars which only very rich dickheads will buy and a lot of badly scripted "humour". I mean; apparently it takes longer to stop and pick up a "dropped" branch than to line your car with plastic sheeting and mulch half a tree...
The Panda vs Ignis bit was a lot more original (although still a bit sillier than necessary) so that saved the episode for me (7/10).
Can't quite put my finger on why but post CHM Top Gear races/competitions have always lacked suspense or a sense of urgency. They seem like no-one is bothered about the result before they even start, so comes over as an anti-climax. The Norway film suffered from this.
Bit of a silly premise for the Suzuki film as well, who'd spend 15 grand on a mini 4x4 where a reasonable sized dog couldn't even fit a dog in the back when they have 100 grand to spend?
Can't comment on the guest segment, haven't watched one for years.
