Which statement is true regarding participation in CAMVAP by car manufacturers?

The statement that only selected manufacturers participate in CAMVAP (Canadian Motor Vehicle Arbitration Plan) is accurate because not every car manufacturer chooses to be part of the program. CAMVAP is designed to resolve disputes between consumers and manufacturers when it comes to vehicle warranty issues. Since participation is not mandatory, manufacturers can choose whether or not to enroll, which often depends on their individual business strategies and customer service policies. This selective participation means that while many manufacturers may choose to join CAMVAP to offer consumers a means of resolving disputes, there are still numerous manufacturers who do not participate, thus leaving it to the discretion of each manufacturer.
