The Depreciation Trap
S-Class models lose value rapidly, making them tempting used buys. However, repair costs remain at flagship levels regardless of purchase price. The W222 generation (2014-2020) is widely considered one of the best S-Class generations ever built, with significant improvements in build quality over the W221.
Examples from 2017 onward benefit from updated electronics and improved reliability. The sweet spot for value is 2017-2019 S 450 and S 560 models with comprehensive service records.
- Dramatic depreciation from new.
- Repair bills stay expensive.
- Complexity increases with options.
Engine Options
The W222 offered a range of engines from efficient fours to thundering V12s. The biturbo V8s in S 560 and S 63 AMG are magnificent but come with corresponding complexity and fuel costs.
| Engine | Years | Power | Character |
|---|---|---|---|
| S 320 d / S 350 d | 2014-2020 | 258hp | Economical luxury |
| S 400 / S 450 | 2014-2020 | 333hp | Balanced V6 |
| S 500 / S 560 | 2014-2020 | 455hp | Smooth V8 grunt |
| S 63 AMG | 2015-2020 | 577hp | Super sedan |
| S 600 / S 650 | 2014-2020 | 523-630hp | V12 presence |
Technology Risks
The W222 introduced many advanced features. These are impressive when working but costly when they fail. The optional Magic Body Control suspension uses cameras to scan the road ahead and adjust suspension preemptively - impressive but expensive to repair.
The extensive electronics package includes multiple control modules that communicate across the CAN bus. When one module fails, it can cascade into symptoms multiple that require specialist diagnosis.
- Magic Body Control: very expensive to repair.
- Multiple screens and electronics.
- Air suspension is almost mandatory to check.
Common Problem Areas
The AIRMATIC air suspension is essentially mandatory on the W222 and requires attention around 50-70k miles. Plan for $3,000-6,000 for a full set of air struts and dampers at independent specialists.
The infotainment system, particularly the COMAND Online unit, can develop faults including screen failures, navigation glitches, and connectivity issues. Repairs can cost $2,000-4,000 for screen replacement alone.
| Component | Typical Issue | Repair Cost Range |
|---|---|---|
| AIRMATIC suspension | Air leaks, compressor failure | $3000-6000 |
| COMAND infotainment | Screen failure, software glitches | $2000-4000 |
| Soft-close doors | Actuator failure | $500-1500 each |
| LED headlights | Module failure, moisture | $1500-3000 each |
| Start-stop battery | No start, accessory battery drain | $400-800 |
Pre-Purchase Inspection Musts
Never buy a W222 without a full diagnostic scan and thorough inspection. Request documentation of all maintenance, particularly air suspension checks and software updates.
Test every feature: all seats (heating, cooling, massage), all doors (soft close), all windows, climate zones, and driver assistance systems. Walk away if anything doesn't operate correctly.
When It Makes Sense
Buy an S-Class if you want maximum comfort and can budget for repairs. Have a specialist inspection done before purchase. The W222 delivers an exceptional luxury experience at accessible prices.
Budget at least $2,000-3,000 annually for maintenance and repairs. Set aside additional funds for unexpected electronic or suspension issues. The reward is Mercedes flagship motoring at a fraction of new prices.
