1. a) It is an unfair or deceptive act to advertise any cash rebates, including, without limitation, a payment or an offset to a consumer or payment to a dealer or third party on behalf of the consumer on the condition that the consumer purchase or lease a motor vehicle, unless the rebate is funded solely by a manufacturer pursuant to a manufacturer's rebate program.
2. b) It is an unfair or deceptive act to advertise a price or amount of an installment payment, wherein rebates have been deducted, unless every consumer seeking to purchase or lease the advertised vehicle is eligible for the rebate.
3. c) The availability of a limited rebate may be advertised if the terms of the limitation are clearly and conspicuously disclosed. It is an unfair or deceptive act to advertise a price or amount of an installment payment in which limited rebates have been deducted, or to advertise a total amount of rebate if a portion of the total consists of a limited rebate.
