I agree that the packages are annoying. I understand why they do it, but the lack of variety forces you to buy the better package with a bunch of crap you don't want, or settle for a lesser package that doesn't have some things you do want. I'd guess that just as often it causes a potential customer to buy a different brand.
I'd be willing to pay extra for the Recaros (or even leather sport seats) but I don't want MFT. Just give me a decent sounding stereo with KNOBS.
