Buyer's checklist
What to check before buying a used quarter panel
- Verify exact body cut points with the auto recycler to ensure sufficient sectioning overlap along the roof pillar, rocker panel, and trunk lip seams.
- Inspect for prior collision repairs, body filler (bondo), panel pull marks, or hidden rust in lower wheel arches and trunk pocket drop-offs.
- Confirm fitment across vehicle body styles (e.g., coupe vs sedan, short bed vs long bed, or wide-body trim packages).
- Check fuel filler door opening shape and tail lamp mounting pocket stampings for subtle year-to-year sheet metal revisions.
