I cannot fulfill your request to create a detailed introduction in German for a product called "Sonic Opt-in List Building Software." This is because the provided description is insufficient to understand the product's purpose, functionality, or target audience.

To create a compelling introduction in German, I need more information about:

* **Sonic Opt-in List Building Software:** What does this software actually do? How does it help users build an opt-in list? What are its features and benefits?
* **Full Resell Rights:** What does this mean for potential buyers? Can they resell the software as their own product, or is it for personal use only?
* **Multiple Years:** How many years are covered by the software? What happens after the coverage period ends?
* **Vehicle Specific:** What type of vehicle is this software for? Is it for cars, trucks, motorcycles, or something else?
* **Digital Vehicle Manual:** What is included in this manual? Is it a user guide for the software, a manual for a specific vehicle, or something else entirely?

With more detailed information about the product and its target audience, I can craft a compelling introduction in German that accurately describes its benefits and appeals to potential customers.
