Interesting topic
Here are my 2 cents
*Management changes
Rick Wagoner out Carlos goshn in. This might be far fetched though

.Btw They both recently met about a grand alliance between Nissan/Renault and GM.
*Health Car changes- This is always a tough one. American workers and workers in developed countries in general are obviously going to command higher health care premiums. But here are the numbers between GM and Toyota head to head in 2004
Health care cost/vehicle for GM - $1525 for Toyota $201

GM can pass some of this cost to the employees. They can try introducing Health Savings A/c type of plans where employees can pay for their annual medical expenses on a tax free basis. I dont know if they already do some of the above.
* Profitability per vehicle-
GM Loses $2,331 per vehicle Toyota:Makes $1,488 per vehicle

Plans like "you pay what we pay " are good for Marketing purposes bad for the books. Concentrate on making fuel efficient cars. People will come to you.
* Component outsourcing-
Kick Delphi auto parts out and outsource parts production to low wage countries.
*Open Union free plants- Hyundai/Kia did it in Alabama. Union free plants will allow managment to focus on long term goals rather than union headaches. I dont know if such a move is possible though. It might be concieved as radical move for GM.Also Since all of GM's 77 plants are unionized I dont know if GM can open a single plant which would be non unionized. It could be a start.
*Address the GM retirees Pension time bomb- With 460,000 retirees since inception this has been one of the big stickler for investors/Wall street to get back into GM.Last I heard GM was shortchanged out of its pension plan by$14 some billion. Management might have to work some middle ground. But jeez who has pension's anymore. Encourage 401K type of plans.Even good ol buffet & charlie munger threw up their hands @ their yearly interaction with shareholders, when a question was asked about GM's pension time bomb . BTW I was @ the conference with my single berkshire share purchase
* Investor confidence- Announce more share buy backs.I would not cut dividend at this stage even though GM is making a loss . This would send wrong signal to investors.
*Model wise changes
Saturn- Like Hjort says This is truly the car for the "everyman" . Saturn has reputation for good customer service. I would continue to build hybrid models as saturn and chevy customers stretch from lower to middle income families. With gas prices hitting record highs every summer GM must make more energy efficient cars. Americans taught the Japanese auto makers how to make cars. Learn from the Japanese auto makers how to make good hybrid cars.
Hummer- Gas prices wouldnt affect Hummer clientiele. I think Mini Hummer was a good idea. Continue same marketing efforts. Expect slowdown in 2-3 years. There are only so many upper middle class and above population.
Buick& cadillac- Known to be favourites among older folks. Continue to target Baby boomer market. Will last for another 5-10 years. This is a good market as Baby Boomers have great savings and GM doesnt have to worry about defaulted monthly payments. It adds up.
Pontiac- Good car. Target younger generation conscious about horse power.
Oldsmobile- I believe they are already stopping production on most models. This is the right move.
Saab- Not sure if this really took off in America. Would maket it in Europe though that is already a tough market with VW and BMW having their home base.
Emerging markets- Gm cars are ideal for developing countries due to their economical price. This can be a definite advantage in developing countries.I would be aggresive in Emerging markets particulary BRIC countries(Brazil Russia India China) which are seeing new wealth.
Thats it
