Maybe I'm a little confused on these new seats. GM told me before I ordered my '12 that all cars get the new seat design. Now, it could be what they meant is revised padding and bolsters for all cars, but only 3LT or better gets special colors or upholstery over that revised padding and whatever. In any event, the seats in my '12 are clearly better than the one in my pal's '08.
As for option packages....I hate 'em, but Chevrolet marketing weenies and dealers love 'em because that way GM can sell you stuff you don't necessarily want.
I ordered our car 1LT, but I would have liked the memory package, however, to get it, I'd have to order heated seats, an expensive sound system and that crappy navigation system, so I live without. Other than the memory package, 1LT gives me most everything I want. I spent the money a lot of other people spend on navi, leather and so forth on a B92 CF hood. Even the base sound system is pretty darn good these days and I'm sorta particular about the sound 'cause when I want to blast Linkin Park, 30 Seconds to Mars, (lately) Florence and the Machine, Sully Erna (Rob's favorite) or Taylor Swift (yes...Taylor Swift! Hey, I have eclectic tastes, ok.), I want it to sound good.
