About the Mercedes-Benz 500
The Mercedes-Benz 500 designation has graced multiple model lines over the decades, most commonly featuring powerful V8 engines. The S 500 (W140, W220, W221, W222) represents the flagship saloon, whilst the E 500 offers similar luxury in a slightly more compact package. Earlier models from the 1990s featured naturally aspirated 5.0-litre V8s producing around 320bhp, whilst modern versions use twin-turbo 4.0-litre V8s delivering up to 455bhp. These cars combine executive comfort with impressive performance, typically reaching 60mph in under 5 seconds whilst offering limousine-grade refinement.
Key variants include the W140 S 500 (1991-1998), W220 S 500 (1999-2005), W211 E 500 (2002-2009), W221 S 500 (2005-2013), and newer W222 S 500 models from 2013 onwards. Earlier air-suspended models are now classic territory, whilst post-2010 examples still command premium prices with modern technology and reliability.
What Affects the Price
Age and generation significantly impact values, with W140 and W220 models now available from £9,000-£18,000, representing the entry point for 500-badged Mercedes ownership. W211 E 500 models typically range from £8,000-£22,000, whilst W221 S 500 examples command £15,000-£35,000. The latest W222 S 500 models dominate the upper price bracket at £35,000-£60,000.
Mileage is critical: sub-50,000-mile examples attract significant premiums, whilst cars beyond 100,000 miles see values drop sharply unless accompanied by exemplary service history. Full Mercedes-Benz main dealer history adds 15-20% to values, particularly on newer models still within warranty extension eligibility. Specification matters enormously—Designo trim, panoramic roofs, rear entertainment systems, and AMG Line packages all add value. Condition of air suspension (costly to repair at £2,000+ per corner), gearbox health, and electronics functionality directly impact pricing. Coupe and cabriolet body styles command premiums over saloons where available.
Buying Tips
Inspect service history meticulously—these engines require regular oil changes (annually or 10,000 miles) and any gaps raise red flags. Check for signs of air suspension failure: uneven ride height, compressor noise, or warning lights. Test all electrical systems thoroughly as complex electronics can be expensive to diagnose and repair. Examine for corrosion around wheel arches and sills, particularly on pre-2010 models.
Budget for running costs: expect 20-25mpg in mixed driving, annual road tax of £415-£735 depending on age and emissions, and insurance in groups 45-50. Specialist independent Mercedes service can halve maintenance costs versus main dealers whilst maintaining quality. Test drive with the ABC (Active Body Control) suspension on various road surfaces—repairs cost £1,500-£3,000. Check cambelt history on pre-2010 engines (chains on newer models). HPI check is essential given the values involved. Private purchases can save 10-15% versus dealer prices but lack warranty protection—extended warranties are advisable on cars over 5 years old, typically costing £800-£1,500 annually.
