That NASA segment with the Demon was really interesting. Chris is right, though, it's still a one-trick pony and always will be, no matter how many iterations there will be of it.
Rory's back down to earth driving normal cars this week with the Stinger, which is pretty cool, but it's a shame it looks nothing like the beautiful concept Stinger GT4. Doug DeMuro has a nice review on it (they're especially good if you like the quirks and features explained), but he never gets to thrash the cars like on these shows. The Hyundai is cool, but I'd still take a Golf over it.
The 2CV piece was a lot of fun. Thought there were some nice, genuine moments in it, like when Chris began giggling when Matt was giving him the stink eye as they drove along, when Matt called him an idiot, and when Chris mentioned the water temperature gauge. There's no denying the charm of the 2CV, and I'd be very happy to see one for real. (my brother did in Vancouver, but I have yet to)
Once again, this season is proving to be very, very good. I'll give this one a solid 8.
