Your owners manual will give you detail on when your car needs specific services done.
It all depends on the actual car itself and how you take care of your car. I recommend that you refer to your service manual for more details.
never
It depends. It is usually the oil change interval is usually indicated in the service manual.
It depends on the mileage of the car and what has or has not be done already.
If your car is under warranty and the service required is covered you will likely need to get the service done by the dealer. Warranties do not cover repairs done if not done at an authorized dealer.
yes
Your owner's manual should have a schedule of service intervals in it.
Any car, and importantly a new car needs often what is referred to as routine service. This can typically include oil changes, tire rotation and balance, brake pad replacement and transmission flush.
Depends on what car and what age/milage it has. Best bet is to invest in a Haynes manual. Tells you the recommended service intervals, what parts you need and how to do it.
It means that you need to take your car to service inspection.
The cheapest car service is to do it yourself, but if that is not an option, check your phone book for local mechanics. They often cost less than the big chain mechanics.
You need to either break in to your car, or have a professional lockout service do it.
