About the Mercedes-Benz 450
The Mercedes-Benz 450 designation covers several high-performance models including the AMG GT 53 4MATIC+ with its 3.0-litre inline-six turbo engine producing 435bhp, and various CLS 450 and GLE 450 variants. These models combine Mercedes' renowned luxury with strong performance credentials, featuring advanced technology including mild-hybrid systems and the latest MBUX infotainment.
The 450 badge typically denotes models positioned between standard variants and full AMG versions, offering an appealing balance of performance and running costs. Most UK examples are well-specified with premium leather, adaptive suspension, and comprehensive driver assistance systems as standard.
What Affects the Price
Model variant has the strongest impact on pricing, with AMG GT models commanding £45,000-£60,000 whilst earlier CLS 450 examples start around £9,000. Age is crucial – 2018-2020 models typically range £25,000-£35,000, whilst 2021-2023 examples command £40,000+.
Mileage significantly influences value, with sub-20,000 mile examples achieving premiums of 15-20% over higher-mileage equivalents. Specification matters considerably – Panoramic roofs, Premium Plus packages, and AMG Line styling add £2,000-£5,000 to values. Full Mercedes-Benz service history is essential and can affect value by 10-15%. Condition of interior leather and paintwork heavily influences private sale prices.
Buying Tips
Verify complete service history with evidence of annual maintenance at Mercedes-Benz franchises or specialists familiar with M256 engines. Check for software updates completed, particularly for the mild-hybrid system. Inspect air suspension for leaks (if fitted) and ensure all electronic systems function correctly – faults can be expensive to rectify.
Budget for premium fuel costs and higher insurance groups (typically 35-50). Extended warranties are advisable given complex technology. Check MOT history for advisory items and ensure tyres are premium brands with good tread. Test drive with attention to gearbox smoothness and any suspension noises. Approved Used Mercedes-Benz examples offer peace of mind with comprehensive checks and warranty coverage.
