The Mercedes S Class average ($410) runs 17% above its median ($350), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
Our guide covers 9 model years for the Mercedes S Class (2015–2024) but only 7 for the Cadillac XT4 (2019–2025), so the Mercedes S Class data reflects a broader range of generations.
The Mercedes S Class strut is interchangeable across 12 model years versus just 7 for the Cadillac XT4 — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.
At Grade A (excellent) condition, the Cadillac XT4 is 73% cheaper ($100 vs $372) — the gap widens compared to the overall median difference.
Buyer's checklist
What to check before buying a used strut
- Check the shaft for pitting or rust — a pitted shaft will chew through the new seal and start leaking immediately.
- Look for oil weeping around the seal area. A light film is normal on older units; dripping means it's spent.
- Confirm whether the strut mount and spring are included, or if you'll need to transfer yours over.
- Match the part to your vehicle's suspension type (standard, sport, electronic/adaptive) — they're not interchangeable.
