Grade A (excellent condition) parts make up 86% of Mercedes S Class listings compared to 71% for the Buick Regal, so buyers looking for top-condition units will find more options on the Mercedes S Class side.
The Mercedes S Class average ($259) runs 15% above its median ($225), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
Our guide covers 8 model years for the Mercedes S Class (2015–2023) but only 6 for the Buick Regal (2015–2020), so the Mercedes S Class data reflects a broader range of generations.
The Mercedes S Class air bag is interchangeable across 13 model years versus just 9 for the Buick Regal — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.
At Grade A (excellent) condition, the Buick Regal is 32% cheaper ($153 vs $224) — the gap widens compared to the overall median difference.
Buyer's checklist
What to check before buying a used air bag
- Verify that the module has never been deployed, repacked, or listed under active safety recalls by cross-referencing the OEM part number and donor vehicle VIN.
- Match interior trim color codes, steering wheel or dash mounting points, and single-stage vs. dual-stage inflator designs across vehicle trim levels.
- Inspect the module backing, clock spring connector housing, and mounting tabs for heat damage, hairline cracks, or tampered wiring harness splices.
- Ensure shipping complies with hazardous material regulations and verify that local laws permit installing salvaged supplemental restraint system (SRS) components.
