Atleast in the Mid-atlantic region, you have to special order NAV. Every dealer shipment seems to come with 1 or less nav equipped car.
MSRP on a fully loaded '02 (5sp, LSD, Full Leather, Nav, Spoiler, mats, wheel locks, etc - no graphite whls) is $35,5. I wouldn't expect to get any more than $500-$1k off msrp at this time. But, there's much more room for negotiations if you get a non-nav equipped car.
So far, the 10 or so '02s I've seen have the same rims as '01s.
