Market analysis
Why does the Mercedes S Class car radio cost more?
A used Mercedes S Class car radio carries a median asking price of $271, which is 110% higher than the Buick Regal at $129. Supply also plays a role: Mercedes S Class has 11,954 priced listings versus 2,124 for Buick Regal, and more listings generally mean more choices and more competitive pricing.
The Mercedes S Class average ($316) runs 17% above its median ($271), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
Our guide covers 10 model years for the Mercedes S Class (2015–2024) 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 car radio is interchangeable across 15 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 47% cheaper ($142 vs $270) — the gap widens compared to the overall median difference.
Buyer's checklist
What to check before buying a used car radio
- Verify anti-theft security unlock code availability or whether the unit is anti-theft VIN-locked to the donor vehicle requiring dealer authorization.
- Match option codes for factory amplified audio systems (e.g., Bose, JBL, Harman Kardon), touchscreens, navigation modules, and steering wheel control interfaces.
- Inspect the rear connector block for bent pins, cut harness pigtails, or damaged antenna and satellite tuner connections.
- Ask for confirmation that the touchscreen digitizer, Bluetooth connectivity, and internal disc drive function without freeze-ups or dead zones.
