3. Convenience: A physical service manual can be used anywhere, unlike digital manuals which require an internet connection or a device to access.

1. Cost: Physical service manuals can be expensive, especially for older vehicles. The cost of purchasing a physical manual may outweigh the benefits for some people.

2. Weight and Size: Physical service manuals can be heavy and bulky, making them less convenient to transport compared to digital manuals.
