A responsible vehicle owner does his vehicle good by regularly bringing his vehicle in an auto shop for services and maintenance, and not just to any auto shop but in one that has been carefully selected and researched on.
You should first note the difference between a car dealership and an independent auto shop where you will have your vehicle serviced before actually going there.
If you buy your car from a car dealership then you will most likely receive a warranty for your vehicle. But it is important to note that the service and repairs eligible under your warranty do not need to be fulfilled at the dealership. Most independent shops are just as capable of performing service and repairs for your vehicle without affecting your warranty.
