btw, FWIW i've read where some folks had their 19" wheels "upgraded" for free to 21" wheels. i may be in the majority, but i do NOT want 21" wheels. no how, no way. I"d likely object and wait for the 19" (note, if i really get offered it for free, and the car sooner, i'd likely cave, like when i say no to dessert at a restaurant....)
the 21" to ME represent:
1) less rubber, more rim damage on my crappy roads, and
2) the need to buy winter tires. Maybe another set of rims, but at the very least either a tire swap, or purchase of all season tires as the 21" only come with summer.
i avoid all that with the 19". yes i think the 19's are ugly, but hey, don't judge a book (or wheel) by it's cover....
