The S400 was the six-cylinder badge on the W222-generation S-Class, sold from 2014 with a 3.0-litre biturbo V6, before Mercedes renamed it S450 for the 2018 facelift with a mild-hybrid boost added. It buys the full-size Mercedes flagship cabin and ride for well under what an S500 or S560 commands, and our UAE stock runs from AED 84500 to AED 84500.
How much does a used Mercedes S400 cost in the UAE?
AED 84500 to AED 84500 on the cars we carry, with service history the main driver of price on a badge with a fairly narrow production run.
Which used Mercedes S400 year should you buy?
A later one within its run — this badge existed from 2014 until the 2018 facelift, when it was renamed S450, so there is no S400 newer than that. Within the window, a post-2017 refresh car gets updated infotainment on the same drivetrain.
How long does a Mercedes S400 last?
The S400s we inspect here run to a median of around 128,000 km, solid mileage for a flagship saloon of this age and consistent with regular highway use rather than a car left parked.
S400 or BMW 530?
The BMW 530 is similar money and shows prior body or panel repair on 52% of cars against the 64% we would expect for saloons of this age and mileage here. The Mercedes C300 is far cheaper, smaller, and retains 50% after five years, for a buyer who wants the badge without the flagship size.
What to inspect on a used Mercedes S400
Book the CarSwitch inspection before you buy, since it confirms the drivetrain and electronics are as sound as the mileage suggests.
