auto service word of caution

So my car is just turning over 60,000 miles and I need to get the appropriate service done as well as service the brake pads.  In my experience the OEM brake pads seem to make a difference so I decided to call a few places to get some pricing.  I called two local auto parts stores and they could not supply me with OEM pads so I decided to call a handful of the local dealers.  The first dealer told me that the pads would be a bit over $100 for the fronts and a couple bucks more for the rear.  The second dealer told me that they would be ~$95 for both and the third told me they would be $90 for the front and slightly cheaper for the rear.  While I was shopping for  pads I thought I’d check on the 60k service.  One dealer told me $1000, another told me $900, and one even told me $650, but depending on the plugs in my car it might be more…probably more… definitely more… around $700 or in the ballpark. 

 

I’d like some explanation of this price difference.  I can somewhat understand the difference for the 60k maintenance.  Maybe one shop does a few extra steps to make sure your car continues to run smoothly.  To be honest I’d consider taking it to the one that said around $700 if it wasn’t for the fact that the service guy didn’t even sound like he knew what my car was (hint: It’s not run of the mill sedan).  The thing that really makes me wonder how much I’m getting screwed when I go to the dealer is the price difference on the parts.  A difference of $40+ between different dealers is not exactly pocket change.  Is there really a good reason for the $40 difference.  Am I getting $40 more brake pads at one location or am I getting screwed by an additional $40?
