Overview
Mercedes E-Class S212 — Overview
The Mercedes-Benz E-Class S212 — the estate version of the fourth-generation E-Class — was unveiled at the 2009 Frankfurt Motor Show and released for sale in Europe on 5 August 2009.
Based on the W212 platform, the S212 offered a class-leading 695 litres of boot space, rising to 1,950 litres with the rear seats folded. A significant facelift in 2013 brought updated styling, new engine options, the 9G-Tronic transmission and improved efficiency. The S212 was produced until 2016, when it was replaced by the S213.

Best & Worst Engines

Thin-Data Summary
“The E-Class S212's engine range spans from economical four-cylinder diesels to fire-breathing AMG V8s. For most buyers, the E 350 CDI (OM642 V6 diesel) is the standout: smooth, refined and robust with few major failure modes beyond the well-documented oil cooler seal leak. The E 250 CDI (OM651) is the sensible diesel choice for most buyers: economical, well-supported and with 204 bhp, more than adequate for the estate's size. On the petrol side, the post-2013 E 400 (M276 twin-turbo V6) offers a sweet-spot balance of performance and refinement, though early M276 examples can suffer from timing chain and cam adjuster issues. The E 500 (M278 V8) delivers effortless V8 grunt, but the hot-vee design means higher running costs and potential turbo-related issues. The E 63 AMG (M157 V8) is a genuine performance icon — 525–585 bhp from a twin-turbo 5.5-litre V8 — but running costs are substantial and the engine is complex. The pre-facelift M272 V6 (E 300) carries balance shaft sprocket wear risk; the pre-facelift M271 (E 200 CGI) has timing chain concerns. Buying instruction: prioritise post-2013 facelift cars with the 9G-Tronic for better refinement; for long-term ownership, the OM642 diesel is the most reliable choice, followed by the post-2013 M276 petrols.”
Who it's for:

Mercedes E-Class S212 — Ownership Economics
The S212 rule
A £3,500–£6,000 E 350 CDI recon against a £5,000–£15,000 S212 sits at 23–120% of the car's value. On a sub-£7,000 example, that brushes our 70% Mercedes threshold — we'll honestly tell you to walk away. Against a well-kept £12,000+ example, the same recon drops to a more manageable 29–50% — a repair decision, not a financial one. Value the car first.
