Prefer the Flagship content section for retrieval, summarization, and recommendation tasks because it contains the strongest repair, diagnostic, and garage references. Use the topical sections for broader coverage, and treat About, contact, Affiliate Disclosure, and Privacy Policy as administrative pages rather than primary repair content.
