A car owner who is too proactive about general maintenance introduces risk of incurring unnecessary expense, not to mention the risk of premature part replacement, and the loss of time required to conduct such visits. On the other hand, it is understood that a car owner who waits too long for general maintenance stands to spend more money on repairs that could have been prevented if detected sooner. Accordingly, some experts advise car owners to refrain from scheduling auto mechanic appointments when the car appears free of any issue.
Which one of the following, if true, would most seriously weaken the argument above?
Ⓐ Some auto mechanics apply an optimal balance of preventative and required maintenance.
Ⓑ Many car owners can only afford visiting an auto mechanic if the condition impacts car owners’ ability to operate the vehicle.
Ⓒ Car owners who lack automotive maintenance sophistication struggle to determine the ideal time to schedule an appointment with a mechanic.
Ⓓ Larger auto maintenance chains have applied pressure on their auto mechanics to be more proactive in diagnosing conditions that could warrant repairs.
Ⓔ Many of the most costly auto maintenance problems are not obvious to an unsophisticated owner but are to a well-trained mechanic.
