How we rank
For each nameplate we take the newest 5 model years whose national median asking price fits under $20,000, then blend four signals, all shown in the table: 30% price headroom (how far the typical asking price sits under the cap), 25% fuel economy (EPA combined, median across the budget years; electric-only models are rated in MPGe and never mixed into MPG math), 25% safety (NCAP overall stars, averaged over rated years) and 20% recency (how new those budget years are — so decade-old cheap metal can't top the list on price alone). A model only qualifies with at least 100 live national listings inside the budget, so everything on this page is actually buyable. Recall and complaint counts are shown for context, not scored — absolute counts scale with how many were sold.
