MERCEDES-BENZ SL CLASS (2016-21) SL400 2DR ROADSTER 3.0 V6 367 GPF SS EU6 GRAND EDITION 9G-T+ AUTO
Buyer's Guide & Data from our Checks
The MERCEDES-BENZ SL CLASS (2016-21) SL400 2DR ROADSTER 3.0 V6 367 GPF SS EU6 GRAND EDITION 9G-T+ AUTO is a premium, two-seat convertible: a stylish grand-touring roadster rather than a practical family car. In the UK, it sits among luxury sports cars, combining open-air motoring with more comfort than a focused track-day model. Its folding roof makes it suitable for sunny drives and year-round outings alike.
The SL400's petrol V6 and automatic gearbox deliver effortless performance. Grand Edition trim brings appeal, while its comfortable cabin suits couples and enthusiasts seeking a touring car, rather than families needing rear seats or drivers prioritising low running costs and daily practicality.
mycarcheck.com records 40 checks across 19 VINs, a modest sample. Average private-sale valuation is £44,200, mileage 15,000, annual mileage 4,000 and previous keepers fewer than one. Like the BMW 6 Series Convertible, the SL offers a distinctly luxury-focused, open-top touring experience for enthusiasts.
A Mercedes SL roadster can hide outstanding finance, insurance write-offs, theft or mileage tampering behind a polished finish. Enter the reg now to check before you buy—miss a warning and it could cost you.
