OK, let me look around...
Found this on FoxNews: GM's pension liability at the end of 2005 was $10.92 billion, according to its balance sheet.
This was from the Washington Post: GM said its pension obligations totaled about $89 billion, with about $90 billion in assets.
Wikipedia said this: The Canadian single payer health care plan saves automakers $1500 per vehicle produced compared to the cost for health care in the United States.
United Transportation Union: GM and other Detroit auto companies face heavy burdens for pension and health care expenses, which they refer to as legacy costs. The companies estimate these expenses cost them $1,800 per vehicle.
Nashua Telegraph: It is estimated GM’s cost per vehicle is about $3,000 more than that of Toyota. The largest contributor to that disadvantage is labor costs.
Here is another: Every Chevy and Buick, each Hummer, Caddy, Pontiac or GMC driven off a dealer's lot by a happy customer this year has cost General Motors Corp. a bundle.
The company lost an average of $1,227 per vehicle in North America in the first half of the year, according to a new report, and company insiders say the hemorrhaging hasn't stopped.
So, who's to know?
I saw $5000 somewhere a long time ago. Perhaps I remember it wrong...maybe it's TOTAL benefits for ALL workers including retirees.
