I think it depends on what you value as important. To each his own.
I intended to get a 2.5 moonroof and convenience package, but it wasn't available.
So, I winded up getting a 2.5 with premium package, because I didn't want to wait 4 weeks for delivery--the premie was in the lot and calling my name...lol.
I'm not a big fan of leather, but it is growing on me and wow, I find myself liking it. The premie has the moonroof, so, still got that. The real difference is about 3 grand, base + moonroof + conv pack or base + premium, moonroof included. So, with the extra 3G, I got the bose speakers, heated seats, 6 CD changer, decent rims (the base come with hub caps).
In terms of the rims, I planned to replace them, but the premium comes with decent rims. I'm not a big rim person, so I will be keeping them. Because I was going to add rims, add 2G to the base price with the advantage being, I would pay for the rims out of pocket and not have it up my payments.
So, pros, cons, you have to decide. I'm happy with the choice I made though.
If I had mod skills and was cool with doing a lot of car upgrade acrobatics, who knows, I may have made a different decision.
I really couldn't wait though...

PS: Bluetooth sounds nice, but not all phones, like my Treo model, are supported right now. You want to check that first, if that is a biggie for you.
