Market analysis
Why does the Tesla Model X control arm cost more?
A used Tesla Model X control arm carries a median asking price of $279, which is 35% higher than the Mercedes S Class at $180. Supply also plays a role: Mercedes S Class has 6,710 priced listings versus 154 for Tesla Model X, and more listings generally mean more choices and more competitive pricing.
Grade A (excellent condition) parts make up 90% of Mercedes S Class listings compared to 45% for the Tesla Model X, so buyers looking for top-condition units will find more options on the Mercedes S Class side.
Our guide covers 10 model years for the Mercedes S Class (2015–2024) but only 8 for the Tesla Model X (2016–2023), so the Mercedes S Class data reflects a broader range of generations.
Only 60% of Tesla Model X control arm listings include a posted price (154 of 256 observed) — the rest are "call for price," which usually signals negotiable or higher-than-average pricing.
The Mercedes S Class control arm is interchangeable across 12 model years versus just 8 for the Tesla Model X — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.
At Grade A (excellent) condition, the Mercedes S Class is 33% cheaper ($186 vs $279) — the gap widens compared to the overall median difference.
Buyer's checklist
What to check before buying a used control arm
- Inspect the arm for subtle bends, hairline cracks, or deep rust scale, comparing geometry carefully against your original unit.
- Examine the rubber bushings for dry rot, tearing, or separation from the metal casing, as worn bushings require pressing out before installation.
- Check integrated ball joints for boot tears and axial play; if non-replaceable, factor in the cost of a unit with a fresh ball joint.
- Verify material type (cast iron, stamped steel, or aluminum) and sway bar link mounting location, which can vary across sub-models and suspension packages.
