Our Verdict
This 2020 Mercedes-Benz E300d AMG Line Night Edition Premium Plus is a solid used buy, with five consecutive MOT passes and no advisories or failures recorded since its first test. The high mileage is the main talking point — at nearly 122,000 miles in under six years, this is a heavily worked vehicle. Buyers should expect some wear items to need attention soon, but the clean test history is reassuring.
Given the high mileage, this E300d is best suited to a buyer who specifically wants a car that has already taken its biggest depreciation hit. Negotiate hard on price — high-mileage executive diesels typically sit well below list values. Ask the seller for full Mercedes-Benz or specialist service history; with over 120,000 miles on the clock, you will want to see evidence of timely oil changes, diesel particulate filter (DPF) attention, and any timing chain or injector work. Inspect the cabin and boot for wear commensurate with high use, and check that all premium-plus equipment (MBUX, air suspension, Burmester audio if fitted) is functioning correctly, as repairs on these systems are costly.
When viewing, ask specifically whether the dual-clutch automatic gearbox (9G-Tronic) has had any software updates or oil changes, as these units can develop jerky shifts if neglected at high mileage. The 2.0-litre OM654 diesel engine is generally regarded as solid, but ensure the car has a recent diagnostic scan showing no stored fault codes, particularly around the AdBlue system which is required for emissions compliance. Also confirm whether the vehicle has been used primarily for long motorway journeys — ideal for diesel engines — or short urban trips, which can clog the DPF and EGR components.
Fuel economy for the E300d is typically in the mid-40s to low-50s mpg on a long run, dropping to the mid-30s in town. With annual mileage that may continue at 15,000-20,000 miles, budget around £2,200-£2,800 per year on diesel at current pump prices, depending on journey mix. Road tax sits in a higher bracket for diesel executive cars of this era, and insurance for the E300 AMG Line is likely to sit in groups 38-42, so expect £600-£900 annually for a standard driver.
Servicing at a Mercedes main dealer or quality independent specialist will cost £400-£600 per visit, with intervals typically every 12 months or 15,000 miles. Larger items such as brake discs and pads, tyres (run-flats on AMG Line variants are pricey at £150-£250 per corner), and eventual timing chain or DPF work should be factored in. Overall, expect a realistic annual running cost of £3,200-£4,000 for a high-mileage example like this, assuming average use and one scheduled service per year.
The MOT history is unusually clean for a car at this mileage — not a single advisory or failure across five tests. That is genuinely positive, but it is important to remember that MOT testing does not cover engine internals, transmission health, or many electronic systems. Focus your inspection on areas the MOT does not check: listen for diesel knock on cold start, check for excessive blue or white smoke, and look for oil leaks around the OM654 engine and turbocharger area.
Inspect the underside for signs of corrosion, particularly around the rear arches and suspension components — Mercedes of this era can show surface rust earlier than expected. Check the AdBlue level and warning messages, as a depleted or faulty system will prevent the car from starting once it registers empty. Finally, examine the alloy wheels for kerb damage (common on AMG Line cars) and confirm the tyre sizes match across all four corners, as mismatched tyres on a high-performance diesel can affect ABS and traction control behaviour.
First registered in September 2020, this black E300d has covered 121,901 miles across its lifetime, equating to around 20,500 miles per year on average — well above the UK average of roughly 8,000 miles annually. The MOT history shows five consecutive passes between February 2024 and March 2026, with zero advisories or failures noted on any test. No aggregate reliability data is available for this specific derivative, making the clean MOT record all the more important to weigh when making a decision. Overall mileage and tax/insurance positioning will be the primary factors shaping running costs for the next owner.
No aggregate MOT reliability data is available for this specific E300d AMG Line Night Edition Premium Plus derivative, so the clean individual record cannot be cross-referenced with broader model trends. The 2.0-litre OM654 diesel engine family is generally regarded as one of Mercedes' more reliable modern units, but high-mileage examples still warrant careful inspection of emissions and turbo systems.
