Market analysis
Why does the Mercedes S Class starter cost more?
A used Mercedes S Class starter carries a median asking price of $125, which is 92% higher than the Infiniti Q50 at $65. Supply also plays a role: Mercedes S Class has 2,194 priced listings versus 623 for Infiniti Q50, and more listings generally mean more choices and more competitive pricing.
The Infiniti Q50 average ($77) runs 18% above its median ($65), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
Only 60% of Infiniti Q50 starter listings include a posted price (623 of 1,033 observed) — the rest are "call for price," which usually signals negotiable or higher-than-average pricing.
At Grade A (excellent) condition, the Infiniti Q50 is 50% cheaper ($65 vs $131) — the gap widens compared to the overall median difference.
Buyer's checklist
What to check before buying a used starter
- Match the bolt pattern and nose cone length — starters from the same engine family may physically bolt up but not engage the flywheel correctly.
- Check the solenoid for corrosion on the electrical terminals.
- Ask whether it was bench-tested. A starter should crank firmly without excessive draw.
- Verify the tooth count on the drive gear matches your flywheel or flexplate.
