This 2009 Mercedes-Benz E-Class E350 CDI BlueEfficiency Avantgarde Saloon offers a compelling mix of performance, reliability, and luxury. Finished in elegant Culprite Brown with a Black leather interior, it has covered just 55,285 miles and comes with an impeccable one-owner history and seven full Mercedes-Benz services, reflecting careful long-term ownership. Under the bonnet is a 3.0-litre V6 diesel engine producing 231 bhp and 540 Nm of torque, paired with a smooth 7-speed G-Tronic automatic gearbox. The result is strong performance and relaxed cruising, with 0–62 mph achieved in under 7 seconds. Despite its power, the BlueEfficiency model offers real-world economy of around 40–45 mpg, helped by aerodynamic tweaks and engine efficiency upgrades. Reviewers consistently praise the E350 CDI for its balance of comfort and performance. Auto Express described the E-Class as having "class-leading refinement and ride comfort," while Top Gear noted it is "solid, dependable, and impressively efficient for a six-cylinder diesel saloon." On the road, it delivers a quiet, composed ride and confident handling, making it ideal for long journeys and everyday use alike. Inside, the Avantgarde trim brings added quality, with high-grade materials, clear instrumentation, and thoughtful touches throughout. The seats are supportive and comfortable, and there's ample space for passengers front and rear. The build quality and layout make it feel like a proper premium vehicle, without being overcomplicated. This particular example stands out not just for its low mileage and Mercedes history, but also for being a rare find in such original condition. With just one owner from new and full Mercedes dealer servicing, it represents a safe, high-quality purchase for anyone looking for a dependable, refined, and capable executive saloon. If you're after a well-maintained, low-mileage E-Class with proven reliability and understated style, this is a car worth serious consideration.
