Mercedes-Benz S-Class buyer's guide
The 2024 Mercedes-Benz S-Class S500 AT is a full-size luxury sedan that suits high-net-worth South African buyers seeking maximum comfort, prestige, and technology in a used executive transport. At 40–60k km, this is a virtually new car still well within its warranty window, offering the flagship Mercedes experience—twin-turbo V8 grunt, air suspension, panoramic OLED displays, and the latest MBUX infotainment—without the steep new-car depreciation cliff. However, this is not a bargain-hunter's purchase: fuel economy hovers around 10–11 L/100 km in real driving, premium fuel is mandatory, and a major service runs R8,000–R12,000. Parts are expensive and lead times can stretch 4–6 weeks for obscure components; independent Merc specialists are abundant in Johannesburg and Cape Town but rare elsewhere. Resale strength is solid in this mileage band because fleet and corporate buyers actively hunt lightly used S-Class models, and the 2024 generation commands strong second-hand appetite. Ownership reality: this is a commitment to regular high-cost servicing, genuine parts, and a comprehensive service history to protect resale. Depreciation over five years from this 2024 point sits around 35–40%, steeper than some rivals but justified by S-Class brand equity and the engineering quality beneath. The verdict is clear—buy only if you have the disposable income for running costs, a trusted Mercedes specialist on speed-dial, and an appetite for the finest German luxury sedan refinement available in SA.
vs BMW 750i xDrive: The BMW 750i is sharper and more driver-focused, with slightly better steering response, but the S500 offers superior ride isolation and a quieter cabin, making it the executive's choice over the enthusiast's.
vs Audi A8 55 TFSI: The Audi A8 is more understated and technology-forward, with an intuitive MMI interface, but the S500 delivers more prestige, stronger resale value in SA, and a more commanding presence.

Common Mercedes-Benz S-Class problems & repair costs
Fuel consumption & premium fuel requirement
Real-world consumption of 10–11 L/100 km combined with mandatory 98 RON fuel means ~R400–R500 monthly fuel bills; budget R6,000–R8,000 per annum for fuel alone at current SA pump prices.
Severity: HighEst. repair: R6,000–R8,000 p.a.Common at: 40k–60k km
Air suspension & electronics complexity
The adaptive air suspension and 12+ integrated electronic modules (steering, climate, drivetrain) mean out-of-warranty repairs can easily hit R15,000–R25,000; sensor faults and suspension refurbishment are common after 100k km.
Severity: MediumEst. repair: R15,000–R25,000Common at: 80k+ km
Parts availability & lead times
Genuine Mercedes parts for S500 can take 4–8 weeks to arrive from Germany; non-critical items are stock in major hubs but obscure electronics or trim pieces require factory order.
Severity: MediumEst. repair: R8,000–R12,000 per serviceCommon at: 20k km intervals
Buyer's inspection checklist
🔧Engine & Drivetrain
Verify turbo boost pressure & EGT readings via OBD-II scan — Twin turbos are stressed at high mileage; carbon buildup reduces efficiency and boost response.
Test transmission shifts under load (light acceleration, gentle braking) — 9G-TRONIC can develop hesitation or hunting between gears if ECU calibration drifts or TCM fluid is degraded.
🚗Body & Exterior
Inspect door & panel gaps; check for respray overspray on trim or badges — 2024 S-Class should have factory-perfect panel alignment; any misalignment or respray signals prior accident or poor repair work.
Examine headlight & taillight lens clarity; test all LED matrix functions — The multi-LED headlight matrix is expensive (R25,000+) and sensitive to condensation or ballast faults.
💡Interior & Electronics
Run through all MBUX functions: voice control, navigation, climate auto-zones, seat memory, panoramic sunroof — Complex electronics are integrated; any non-responsive module can cost R5,000–R15,000 to diagnose and repair.
Test air suspension height adjustment (low, comfort, sport); feel for even leveling over bumps — Suspension compressors and valve blocks degrade; uneven ride or limp-home height mode suggests imminent R12,000–R18,000 repair.
📋Service History
Demand full official Mercedes service record; every 20k km service documented with stamped invoices — Out-of-warranty (post-160k km) resale value collapses without proof of regular dealer servicing; independent work flags questions about battery, software, or suspension work.
Verify no software recalls, module coding issues, or pending TSB (Technical Service Bulletins) via Mercedes portal — 2024 models occasionally receive software updates for stability or driveability; unresolved TSBs can hint at unrepaired mechanical niggles.
Owners praise the S500's effortless power and serene highway refinement, but acknowledge fuel costs and complex electronics as real drawbacks in daily use. (78/100 owner approval)
👍
Unmatched refinery & silence
The air suspension isolation and sound-deadening make highway cruising at 120 km/h feel like floating; twin-turbo V8 is characterful yet smooth, never harsh or intrusive.
👍
Strong resale & fleet credibility
Corporate and executive buyers actively hunt the 2024 S500; low-mileage examples retain ~62–65% of retail value at 5 years, better than rival Audis and BMWs in SA.
👎
Astronomical running costs
At current fuel prices (R27–R29/L × 11 L/100 km) and R8k–R12k biennial services, annual costs easily exceed R80,000 excluding unexpected repairs.
👎
Electronic gremlins & repair delays
Panoramic sunroof jams, climate zone faults, and air suspension valve glitches are not uncommon by 80k km; parts lead times and specialist availability vary wildly by province.
