Which of these actions is NOT considered a deceptive trade practice?

Delivering goods as promised is a clear indication of compliance with ethical business practices. In the context of motor vehicle sales, fulfilling the terms of a sale by delivering the vehicle as agreed not only establishes trust with the buyer but also aligns with legal standards for honest transactions. This action exemplifies transparency and reliability in business dealings, making it the opposite of a deceptive trade practice.

In contrast, actions like guaranteeing loan approval without official confirmation, accepting trade-ins while the sale is still pending loan approval, and failing to disclose a vehicle's salvage history can all mislead consumers, potentially resulting in financial loss or misunderstanding. These practices violate consumer trust and can lead to legal repercussions under trade practices regulations. Thus, delivering goods as promised stands as the only action among the provided options that aligns with proper business ethics and regulations, which is why it is not categorized as a deceptive trade practice.
