Genuine, aftermarket, used original or refurbished — which should you buy?

The five conditions we sell

• Genuine OEM · new — made by or for the vehicle manufacturer, in the maker's box. Best for safety-critical and electronic parts.
• Aftermarket · new — reputable brands (Bosch, Mahle, Febi, Lemförder…). Great value for service items.
• Used original — genuine parts removed from donor vehicles, inspected and photographed. The only option for many discontinued items.
• Refurbished original — used originals rebuilt to spec (alternators, calipers, lamps).
• Performance — upgrades over the factory specification.
