After driving a 2002 WRX, 2009 Forester XT (turbo), a tuned 1990's Altima (w/ slip diff), I'm happy to say the new Si is the best of them all!
Road & wind noise are minimized, hearing only the rough & grumble growl of the engine.
buttery smooth clutch with short throws is easy & fun.
Front slip diff performs remarkably, & even makes driving on all season 17" / 45s in snow & slush tolerable (I normally have snow tires).
Ergos are nice, especially the back split fold down seats, center arm rest, matched int colors, & standard back-up camera.
Of course there could be more space & luxury, like an Acura TSX or Audi A4.
But then again, you won't pay $30k++ for the Si!
Front-end slip diff; remarkable 2.4L engine (best of all: NO turbo lag!); useable low rpm torque and grunt; easy radio and user interfaces; terrific turn radius and maneuverability; back-up camera; center armrest & console; exterior looks; unique polar orange color; split fold-down back seats; very good gas mileage (when you don't push accelerator, can get 33mpg highway).
Not much to suggest.
Maybe a skosh more headroom, and less contoured front sport seats (how many people really race their Si?).
