Could you build this?
Partial The question-tree interface and report flow are easy to vibe-code, but the value rests on a corpus of 12,600+ repair guides and safe-to-drive judgments that someone must research, write, and keep current.
What it would actually take: The app itself is a decision-tree engine over a structured knowledge base, likely backed by a database of symptoms, parts, and diagnostic checks with an LLM or rules layer for question flow. The hard parts are building and maintaining the diagnostic content (which needs automotive expertise and sourcing) and validating the 'safe to drive' guidance so it doesn't mislead users. A real version needs a mechanic or engineering content team plus a verification process, not just code.
