I'm sort of new to the Z3 world. I bought a 98 Z3 in April with 34K on the odometer. I'm nearing the time to take it in for an oil change, and I was told that it was time for my "Inspection II" ($598) as well as a brake fluid change ($96). My question is are these really necessary? That's a lot of money to pay for a car with less than 40K on it. What exactly do they do for $598 and can it be done anyplace other than a BMW dealership? Any help, comments, or advice would be greatly appreciated.

Thanks!
