What is the difference between maintenance and repair?

There is a subtle difference between preventive maintenance and regular scheduled
maintenance, both are equally important when it comes to car safety.
Delaying Preventive and/or Scheduled maintenance can ultimately cause more economic strain
as well as unnecessary risk to the driver and passengers.
Almost everyone understands the need of scheduled maintenance, like an oil change,
most people do it regularly, when it comes to preventive maintenance they don't realize
that those $250 today to replace a component
like a worn front wheel bearing, could become hundreds of dollars tomorrow when the wheel falls off the axle and
break more components of the front end system (hopefully not at high speed).

The average car in America is 9 years old you must rely on
proper maintenance to keep your vehicle running at peak operating conditions.
The longer you take to check that squeaky noise when you push
your brakes or the vibration that goes away when you accelerate, the more
costly your bill will become for neglecting your vehicle, no; it won't be the
Car repair shop fault. You know your car and you need to listen when it speaks to you.
