The S400 was Mercedes' hybrid-assisted six-cylinder S-Class, built on the W222 platform from 2014 with a 3.0-litre biturbo V6 and mild-hybrid support. In Saudi Arabia it gives full S-Class size and comfort with lower running costs than the V8 versions.
How much does a used Mercedes S400 cost in Saudi Arabia?
Our 7 listings are 2017-era cars, priced from SAR 87000 to SAR 120000 depending on condition and how the hybrid system has been maintained.
Which used Mercedes S400 year should you buy?
2017 is a pre-facelift W222, which ran from 2014 until Mercedes revised the range in 2018 with the newer EQ Boost system and updated infotainment. A facelifted 2018-onward car is the more modern version underneath if you can find one; a 2017 car is the same platform without the later updates.
How long does a Mercedes S400 last?
Comfortably long, on the evidence we see. The cars we inspect come in at a median of around 125,000 km and are still well within a normal working life for the platform. The hybrid battery and starter-generator are the components worth confirming, more than the odometer reading itself.
Anything else worth knowing about the Mercedes S400?
A BMW 740 costs similar money, and our inspections find a mechanical fault on 11% of them, against the 20% we would expect for large luxury saloons of this age and mileage here. The Lexus ES250 costs more but is the more dependable choice if the badge matters less than peace of mind. Within the Mercedes range, the S350 is the cheaper, non-hybrid alternative.
What to check on a used Mercedes S400
- Hybrid battery and starter-generator health check.
- Air suspension for sagging, leaks or warning lights.
- 7G-Tronic gearbox shift smoothness under load.
- Full service record from an authorised centre.
