Funny video agree about comparisons seeming odd ... Although really I was in the same boat a few months ago when I was buying my Boxster... thinking about Nissan 350 or 370, BMW Z4, Boxster etc... and also reading a bit about future specs of the Scion... Glad I got my Boxster.
All that said I'd love to trade my Scion XD for a FR-S at some point. Heh.
