Used 2007 BMW 5 Series

Distinctively styled, capable of accommodating four adults in comfort and possessing an enticing mix of sportiness and luxury, BMW’s 5 Series is universally regarded as a modern-day success symbol. Equally important, it has an uncanny ability to connect with its owners on a far more emotional level than do rivals like the Acura RL, Audi A6 and the Mercedes-Benz E-Class. While the six-cylinder 525i/530i models account for the lion’s share of sales, it’s the V8-powered 550i that smartly elevates both passenger pampering and absolute performance. Prime among the many significant features that help keep it true to the marque’s "Ultimate Driving Machine" tag, this premium rear-wheel-drive sedan gives buyers the unusual choice of a slick-shifting manual transmission or an automatic.

Even in base form, the 550i is a driver’s delight, thanks in great measure to its potent V8 and the Dynamic Stability Control (DSC) that integrates its computer-controlled stability enhancement with traction control and anti-lock brakes (ABS). Our test car also had two key options: Active Steering and the Sport Package. The former varies the steering ratio in a way that makes the vehicle easier to maneuver in close confines while helping it feel more stable when cruising at higher speeds. The latter – which includes BMW’s Active Suspension, Active Roll Stabilization and 18-inch run-flat tires – imparts an overtly sporty feel to the 550i – although some owners may find the more supple feel of the base suspension more to their liking.

Elegantly understated, the 550i’s cabin is trimmed in Dakota premium leather and poplar or maple wood keyed to black, grey, auburn or tan color motifs. Front-seat occupants enjoy comfortable and supportive 10-way power front buckets while the spacious rear quarters offer a split-folding rear bench with sufficient room to accommodate two full-size adults or a trio of kids. Highly-legible analog gauges provide basic information on vehicle speed, engine revs and fuel level, but the centerpiece of the dash is a color LCD screen connected to the love-it-or-hate-it iDrive integrated input system that uses a central rotator knob to control everything from the audio and air conditioning to the optional navigation and adjustable suspension systems.

Visually, the latest 5 Series stands in stark contrast to BMWs of the past, with subtle corners and simple lines giving way to sharp-creased edges and cat’s-eye headlight lenses that, with the 550i, house corner-following active bi-xenon lamps. Several heritage details remain, such as the twin-kidney grille and dogleg kink in the C-pillar. But with its bustle-back trunk and sculpted side panels, the 550i has definitely moved to new design territory.

Xenon Adaptive Headlamps
Optional on lesser 5 Series models but standard on the 550i, these ultrabright illuminators shine with an intense blue-white beam, that closely approximates natural daylight, and also turn with the steering wheel to help you see further ahead into a corner.

Optional Multi-Contour Seats
While the standard 10-way power front buckets deserve kudos for comfort and support, the optional 20-way multi-contour units with articulated backrests, variable side and thigh bolsters and four-way lumbar support raise the long-distance travel experience to an entirely new level.

Heading the 550i’s long list of standard equipment is premium leather upholstery and wood interior trim, dual-zone automatic climate control, 10-way power seats with power lumbar support, a power tilt/telescoping leather-wrapped steering wheel with touch controls, iDrive multifunction integrated controller, 10-speaker AM/FM/CD/MP3 audio system, keyless remote entry and a power moonroof. Functional touches include the comprehensive Dynamic Stability Control (DSC) system that also integrates the 550i’s traction control and advanced anti-lock brakes (ABS), bi-xenon adaptive headlamps, dual heated power mirrors with a "look-down" feature that helps in parallel parking, Park Distance Control and fog lamps. Front and front-side airbags are complemented by BMW’s front and rear side-curtain head protection airbag system.

Extras for the 550i include either BMW’s six-speed Sequential Manual Gearbox (SMG) or the STEPTRONIC automatic transmission at no additional charge, a voice-activated navigation system, distance-maintaining "active" cruise control, Head-up Display, speed-sensitive Active Steering, rear side-impact airbags, keyless entry and start, 20-way power multi-contour seats and SIRIUS Satellite Radio. Key group upgrades include the Sport Package (sport suspension, Active Roll Stabilization, 20-way multi-contour seats and 18-inch run-flat performance tires), Premium Sound Package (LOGIC7 Surround Sound audio with glovebox-mounted six-disc CD changer) and the Cold Weather Package (heated front seats and steering wheel and a high-pressure headlight cleaning system.

The 550i shares its 4.8-liter DOHC V8 with the larger 7 Series sedan. Making a smooth 360 horsepower and 360 pound-feet of torque, this free-revving engine is fortified with BMW’s Valvetronic variable intake valve lift and Double VANOS variable intake/exhaust valve timing, advanced technologies that help to quicken its throttle response and enhance overall fuel efficiency. BMW claims zero to 60-mph times of around 5.5 seconds, either with the standard six-speed manual transmission, the six-speed Tiptronic automatic or the racing-style, six-speed Sequential Manual Gearbox (SMG).

Our Expert Ratings come from hours of both driving and number crunching to make sure that you choose the best car for you. We comprehensively experience and analyze every new SUV, car, truck, or minivan for sale in the U.S. and compare it to its competitors. When all that dust settles, we have our ratings.

We require new ratings every time an all-new vehicle or a new generation of an existing vehicle comes out. Additionally, we reassess those ratings when a new-generation vehicle receives a mid-cycle refresh — basically, sprucing up a car in the middle of its product cycle (typically, around the 2-3 years mark) with a minor facelift, often with updates to features and technology.

Rather than pulling random numbers out of the air or off some meaningless checklist, KBB’s editors rank a vehicle to where it belongs in its class. Before any car earns its KBB rating, it must prove itself to be better (or worse) than the other cars it’s competing against as it tries to get you to spend your money buying or leasing.

Our editors drive and live with a given vehicle. We ask all the right questions about the interior, the exterior, the engine and powertrain, the ride and handling, the features, the comfort, and of course, about the price. Does it serve the purpose for which it was built? (Whether that purpose is commuting efficiently to and from work in the city, keeping your family safe, making you feel like you’ve made it to the top — or that you’re on your way — or making you feel like you’ve finally found just the right partner for your lifestyle.)

We take each vehicle we test through the mundane — parking, lane-changing, backing up, cargo space and loading — as well as the essential — acceleration, braking, handling, interior quiet and comfort, build quality, materials quality, reliability.
