why are you even ASKING such a question?
INTERIORS ARE EVERYTHING!!!!!!!!!
how do you suppose VW revived itself? Why do fresh out of college females dump 28 thou on a tiny Jetta. Because its prim and proper and JUST SO on the inside. How do you suppose Audi became who it is? INTERIORS!!!
how do you suppose Lexus got so popular?
If you look at the car brands and models that create large buzzes and make large profits, its usually cars and such that have nice materials and appeal to women. Now guys like good interiors too.
Sadly, GM has never gotten that. Really if GM nailed interiors, exterior styling, powertrains, and features, they would go somewhere.
let's use the 07 tahoe/yukon as an example. if you see one with tan/black interior and leather it looks great. grey cloth/grey...not so great. look at the magazine test of that vehicle. it gets RAVE reviews. First GM product in a long time with universal praise of the interior.
Now, you don't think there is a lsight coincidence between that and how they rate the car overall? If the Tahoe had a marginal interior like the usual GM, they would berate the hell out of the car, and that would kill sales.
Watch people at the autoshow. Most of them are clueless. But they ALL judge how much they like a car, after they get in it and scope out the interior. The cars you hear folks comment on and praise have the nice interiors and they seemingly make their whole judgment about the car on that, and price.
interiors are more important then powertrains to many buyers (i.e women).
