I see LOTS of Altimas and Muranos. The new Pathfinder I'm seeing more, and the occassional Quest.
I see EXTREMELY few Titans and Armadas. The Sentra I don't even notice, thank God. Maxima sales have been slow and don't see too many of those - prob more Z-Cars 'round these parts.
X-Trails are popular too.
Altima sales have been extremely strong. Since intro, I think Nissan keeps growing sales of that thing. Nationally, Accord, Camry, Altima I believe, with Mazda6 trailing by a fair margin and alongside a number of others, as the 6 does well in ON and QC but not elsewhere.
Altima has come from nothing to really put pressure on the previous big-2 Japanese mid-sizers. It's done well, and has stood out.
