Whether the loaner costs or not is up to the dealer. The one I go to charges a $6 gas fee and that is it. $550!!!!! I got it done at the dealer for right at $300. In your cars owners manual is a list of the services to be performed at inspection 1 and inspection 2 services (60K is an inspection 2). If I remember correctly the only differance is in inspection 2 they change the air filter. Ask what an inspection 1 costs it should be around $300 a little under I think, then ask them why the air filter is $250, the service manager will look at you funny, the "other" BMW dealer in town gave me the same perplexed look when I asked him to justify the quote.
Yes they will nit pick the car most likely telling you that new wiper blades are needed and that they can install them for $50, but you are under no obligation to have anymore work than the agreed on inspection performed. You can most likely do alot of what they reccomend yourself or have it done at an independant garage for less.
