Best Car Reviews - 2007 Mercedes-Benz CLS550

Rate this article Choose 1-5 stars.

Introduction

The 2007 Mercedes-Benz CLS550 is a stylish luxury four-door coupe aimed at drivers who want V8 performance and Mercedes-Benz comfort in a more dramatic shape than a traditional sedan. It replaced the earlier CLS500 in North America, bringing a more powerful 5.5-liter V8 and the distinctive low-roofed CLS silhouette. Although sometimes grouped in compact-car databases, it is best understood as a large premium four-door coupe with limited rear-seat practicality.

Design and Exterior Features

The CLS550 combines a long hood, frameless side windows, steeply raked roofline and short rear deck to create one of the most recognizable Mercedes-Benz designs of its era. For 2007, the key improvement was beneath the hood: the CLS500 gave way to the more powerful CLS550. The body remains sleek rather than aggressive, with a wide grille, sculpted fenders and a coupe-like profile that separates it from the related E-Class sedan.

Interior and Comfort

The cabin is driver-focused and richly finished, with leather upholstery, real wood trim and a broad center console separating all four seating positions. Front-seat comfort is a major strength, particularly for long motorway trips, while the rear compartment is best treated as seating for two adults rather than a conventional three-person bench. The low roofline and sloping rear glass compromise headroom and outward visibility compared with a traditional luxury sedan.

Performance and Handling

The rear-wheel-drive CLS550 uses a naturally aspirated 5.5-liter, 32-valve V8 producing 382 horsepower at 6,000 rpm and 391 lb-ft of torque from 2,800 to 4,800 rpm. A seven-speed automatic transmission sends power to the rear wheels. Mercedes-Benz quoted a 0-60 mph time of 5.4 seconds, giving the car effortless passing power and strong high-speed cruising ability. Its broad torque delivery and adaptive transmission suit relaxed driving, while the chassis remains composed on winding roads. Fuel use is substantial: published Canadian figures list 15.6 L/100 km city and 9.9 L/100 km highway; the supplied combined figure of 18.594375 mpg is approximately 12.6 L/100 km.

Technology and Connectivity

Technology was advanced for 2007, though it now feels dated beside modern smartphone-based systems. The CLS550 offered the COMAND interface, navigation, CD audio, steering-wheel controls and a multifunction display for vehicle settings and trip information. Available equipment included a phone interface, Parktronic parking assistance, rear-view camera equipment in some configurations, and Distronic adaptive cruise control. Buyers should confirm the equipment on an individual used car, as many desirable features were optional.

Safety Features

The 2007 CLS550 includes a strong suite of era-appropriate active and passive safety equipment. Standard systems include electronic stability control, traction control, anti-lock brakes, Brake Assist, front and side airbags, window airbags, PRE-SAFE occupant preparation and NECK-PRO active front head restraints. Mercedes-Benz also fitted Adaptive Brake and flashing brake lights to help warn following traffic. A current CLS-specific IIHS or NHTSA crash-test rating for this model year should not be assumed without checking the applicable database.

Pricing and Variants

The CLS550 had an original U.S. base MSRP of approximately $67,675 before destination, options and the applicable gas-guzzler tax. The 2007 CLS range consisted of the CLS550 and the much more powerful CLS63 AMG. The CLS550 competed with V8 luxury sedans such as the BMW 550i, Audi A6 4.2 and Lexus GS 460, but its coupe-like styling and four-seat layout made it a more specialized choice.

Pros and Cons

Pros

Striking design that remains distinctive
Powerful and smooth naturally aspirated V8
Fast acceleration and relaxed motorway performance
High-quality materials and a luxurious front cabin
Strong safety technology for its model year

Cons

High fuel consumption and premium-fuel requirement
Rear headroom, rear access and rear visibility are limited
Optional technology feels old by current standards
Complex luxury systems can be expensive to repair
Maintenance costs can exceed those of mainstream alternatives

Maintenance and Common Issues

A single verified yearly maintenance-cost figure is not available because costs vary sharply by mileage, service history, location and whether major repairs are required. A pre-purchase inspection by a Mercedes-Benz specialist is essential. Common owner-reported concerns for the C219 CLS generation include AIRMATIC air-strut or compressor faults on equipped cars, aging electrical and infotainment components, seven-speed automatic shift-quality or conductor-plate issues, oil leaks from aging engine seals, and M273 V8 timing-system or balance-shaft concerns on affected early engines. Service records, diagnostic scans and evidence of preventive maintenance matter more than odometer mileage alone.

Rating

Overall rating: 8.0/10. Design: 9.3/10. Comfort: 8.4/10. Performance: 8.7/10. Technology: 6.8/10. Safety: 8.0/10. The CLS550 earns its score through style, V8 character and grand-touring comfort, while its age, fuel use and repair exposure prevent a higher overall rating.

User Reviews and Feedback

Owner feedback commonly highlights the CLS550 as an emotional, stylish alternative to a conventional luxury sedan. Satisfaction is highest among owners who buy well-maintained examples, budget for specialist servicing and value the V8 driving experience over low operating costs.

The V8 is widely appreciated for smooth, immediate power
Front-seat comfort and long-distance refinement receive positive feedback
Rear-seat access and headroom are frequent practical complaints

Summary

The 2007 Mercedes-Benz CLS550 is best suited to drivers seeking a distinctive V8 luxury car with genuine performance, refined cruising manners and dramatic four-door-coupe styling. It remains appealing as a used purchase when condition and service history are exceptional, but it is not a budget luxury car: prospective owners should reserve funds for premium fuel, specialized maintenance and age-related repairs.
