Supply also plays a role: GMC Sierra 1500 has 3,107 priced listings versus 685 for Infiniti QX80, and more listings generally mean more choices and more competitive pricing.
Grade A (excellent condition) parts make up 74% of Infiniti QX80 listings compared to 56% for the GMC Sierra 1500, so buyers looking for top-condition units will find more options on the Infiniti QX80 side.

Buyer's checklist
What to check before buying a used window regulator
- Distinguish between power and manual regulators, and confirm motor wire connector pin counts (e.g., 2-pin basic vs 6-pin express auto-up/down with anti-pinch).
- Inspect regulator cables for fraying, rusting, or derailment from plastic pulleys, and check scissor gear teeth for stripping or binding.
- Check glass attachment clips or mounting clamps to ensure plastic snap tabs aren't brittle or broken.
- Verify front door vs rear door and left vs right side specific mounting hole patterns, as regulators are non-interchangeable across doors.
