My dealer says GM recommends that every 30,000 I should perform the following mantenance:

Clean Fuel Injectors, Replace fuel filter, Replace PCV valve and air filter, Front wheel alignment, and Automatic transmission flush.

And then at 40,000, they say to flush the brake system and power steering system.

I understand the fuel filter and pcv valve, but is it really necessary to do the Auto transmission flush, front end alignment, and flush the brake and power steering systems?

They want $409.95 to do the 30,000 stuff, and then another $159.95 to do the 40,000 stuff.

I'm around 35,000 now and am thinking about knocking all this stuff out at once. I'm definately not having the dealer do all this stuff (find someone cheaper), but do you think all this is necessary?

Which ones of these do you think I should do?
