What drives the price
Genuine, OEM supplier, aftermarket
Genuine interior parts match the grain and the color code. On a visible trim piece that is the whole job — a near-match reads worse than the broken part.
Regulators, motors and switch blocks are widely available in the supplier line. Same mechanism, same connector, much shorter invoice.
Aftermarket is safe on clips, cup holders and hidden brackets. Anything the customer touches or sees every day, buy once in the correct color code.
