Inspection II - Bad or fair price?

[thebluedog]

Hey Guys -
My local Indy shop quoted me $900 for Inspection II - but wait, I know that's a little high, but they include a little more than the traditional Inspection II from what I've read on this forum.
Still costly, I agree, considering a lot of Inspection II is simply inspecting BS.
But here's what they are offering for $900 in terms of tangibles:
*New NGK plugs
*New fuel filter
*Replace transfercase fluid
*Replace differential fluids
*BMW brand oil change/filter
**Price does not include new air filter and micro filter since I told them I just replaced those myself
I asked the SA how much it would cost for those services individually. Here's what they would cost:
*New plugs - $300
*Fuel filter - $200
*Transfercase fluid - $121
*Differential fluids - $121
*BMW brand oil change/filter - $100
Total - $842
$842 is less than the $900 for the all inclusive Inspection II, but supposedly, they are supposed to closely inspect all aspects of the car for $900 - under Inspection II.
I'm sure a lot of people see these as DIY - but I am mechanically challenged except for replacing things like the air and micron filter, oh and the wiper blades.
I think the main difference is that they include replacing the transfercase fluid and differential fluids. I'm at 63k miles and think it's probably a good idea to replace those fluids. Not sure what BMW recommends.
So, is this a bad or fair deal?

Thanks for your input!
