Just watched the Vettel part of that show (http://www.youtube.com/watch?v=eBUr6sDYcms&feature=youtu.be). Really nice guy. Intelligent, competative, funny, cunning. I agree with everyone wanting to see him having more of a fight on his hands, but he had been showing that in at least half of the races this year, so all is not lost.
As for the Ferrari 458 vs. McLaren MP4-12C. The Ferrari is ugly, overstylized. And its controls are just ridiculous (blinkers turning with the wheel, meh). The McLaren is a great piece of engineering, smooth looks and nice curves. I like that. Oh, and it is only about 2-3 seconds faster around that Top Gear track, driven by the Stig! Not too bad for a cheap newcomer then!
