Supply also plays a role: Mercedes C Class has 4,496 priced listings versus 2,683 for Kia Optima, and more listings generally mean more choices and more competitive pricing.
Our guide covers 10 model years for the Mercedes C Class (2015–2025) but only 6 for the Kia Optima (2015–2020), so the Mercedes C Class data reflects a broader range of generations.
The Mercedes C Class headlight assembly is interchangeable across 15 model years versus just 7 for the Kia Optima — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.
The Kia Optima has 8 known trim variants compared to 5 for the Mercedes C Class, which means buyers need to be more careful about matching the exact engine or drivetrain configuration on the Kia Optima.
Buyer's checklist
What to check before buying a used headlight assembly
- Check for lens clarity — cloudy, yellowed, or hazed lenses reduce light output and can fail inspection.
- Look for moisture damage or watermarks inside the housing. A dried-out water line means a broken seal.
- Confirm whether the unit is halogen, HID/xenon, or LED — the wrong type won't plug in correctly and may need different ballasts.
- Inspect the tabs and mounting points for cracks. Headlight tabs are fragile and a broken tab means the assembly won't seat properly.
