Looks like the parachute was vastly undersized. Both the absolute and adjusted numbers showed downward acceleration. The results for the three largest Japanese companies were off by ~28%. GM, F, and the company formerly listed as C saw declines of 49%, 41% and 55%. I don't see how C can survive on those numbers.
Both Hyundai-Kia and Subaru had modest increases, which in this environment is like doubling sales. For individual brands, Chrysler saw the worst, with a staggering 69% decrease from January of 2008. Since January of 2006 Chrysler sales have fallen by 78%, beating Pontiac by a few points for the worst performance among active brands.
