service center said it costs 149.99. Is it necessary
(1) Answer
It's necessary ,for them to be more profitable.(MY OPINION).THAT SAID,? how well have you really maintained your car? Factory filters ,proper mileage intervals for service ,or do you wait for problems ? Know what I mean? a nice respectful way.
