Its sort of up to you if you want to spend the money.
At 15k miles you should have nothing wrong with your car..
I got my car with 27k on it and skipped the 50k service and instead got it around 70k.. I think I spent $600 or so to have everything checked out. I felt like I overpaid big time and told myself I wouldn't do that again. Car felt no different, all I noticed was new oil and windshield wipers.
Theres a bunch of threads on this - Do some searching
The minor stuff you can check out yourself.
