Buyer's Guide & Data from our Checks
The MERCEDES-BENZ S CLASS (2017-20) S400L 4DR SALOON LWB 2.9D DPFR SS 340 EU6 GRAND EDITION REAR LUXURY LOUNGE 9G-T+ AUTO is a full-size, long-wheelbase luxury saloon, sitting near the top of the UK executive-car market. Its extended cabin and rear-focused Grand Edition specification make it especially appealing when passenger comfort matters as much as the drive.
It suits business users, chauffeur work and buyers who regularly travel with adults in the rear, while its size and running costs are less ideal for tight city parking or budget motoring. mycarcheck.com has one lookup for one VIN, so its figures are a very small snapshot: the recorded average private-sale valuation is £44,900, with zero previous keepers shown.
Compared with BMW 7 Series and Audi A8 rivals, it is known for a serene ride, polished presentation and generous rear-seat luxury; check condition, history and servicing before buying, as with any used flagship.
Considering a Mercedes S-Class? Outstanding finance, write-offs, hidden damage, mileage discrepancies or theft could turn a luxury buy into a costly mistake. Enter the reg now and check before you commit.
