The Mercedes E Class average ($503) runs 15% above its median ($438), 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 E Class (2015–2025) but only 7 for the Cadillac XT4 (2019–2025), so the Mercedes E Class data reflects a broader range of generations.

Buyer's checklist
What to check before buying a used door mirror
- Confirm the feature set: power fold, heated, blind-spot monitoring, turn signal, and auto-dim vary by trim.
- Test the power adjustment motor if possible — a mirror that moves on one axis but not the other needs a motor replacement.
- Check the connector pin count. Mirrors with more features have more pins, and a mismatch means missing functions.
- Look for cracks on the mirror glass backing plate. A cracked plate causes the glass to vibrate at highway speeds.
