When must you give the customer two copies of a notice of the "cooling off" period?

Answer: A — After the customer makes the first payment

After the customer makes the first payment is the correct timing to give the customer two copies of a notice of the "cooling off" period because that is the point where the customer is financially invested in the transaction and should be fully informed of their rights. Options B, C, and D are incorrect because they are either before the customer has made a commitment (option B) or too late in the process (options C and D). Giving the customer two copies of the notice after the contract is negotiated or when it is signed would not allow them enough time to review their options and potentially cancel the transaction if they choose to do so. Similarly, giving them the notice after the vehicle is delivered would not give them enough time to make an informed decision. As such, the only appropriate timing for giving the customer two copies of the notice is after they have made the first payment.
