Thank you for taking a moment to visit our latest drop top European Grand Touring car offering. This 2004 BMW 645ci Convertible comes to you in great condition and loaded with desirable features. With only 63,000 ONE OWNER miles, it has tons of life left in it. This car has been well cared for both cosmetically as well as mechanically and is simply ready for a new driver. This car was custom ordered with the richest color combination availabel and nearly every option available in 2004.  This car was built for BMW's European Delivery Program and has been dealer serviced since its birth in May 2004.  This car has had no expense spared in its care and maintenance.  Its garage companions have been the likes of Ferraris and Bentleys to name a few.  My point is not to brag, but to accurately convey the reality that "there is a difference between this car and the rest of the pack." Owners of fine automobiles tend to be more fastidious about their maintenance than ordinary drivers.  

Review: 

15 years after the retirement of the original 6 Series (1977-1989), BMW will once again sell a high-dollar convertible that combines all the best the company has to offer in performance, luxury and style — complete with the ability to seat a companion or baby seat in its 2+2 occupant compartment.

Chief rival Mercedes-Benz has made plenty of money off well-to-do buyers who want vehicles that fit this profile, and it's no coincidence that BMW's new 645Ci convertible slots just about halfway between the much desired CLK500 and the upper-crust SL500 in length, width, wheelbase, curb weight and MSRP. This tells you plenty about the overall dimensions of the 645Ci — about the same size as the 5 Series sedan — and what it will take to get one — upwards of $80,000.

More interesting is what this casual comparison doesn't tell you. Jaguar, Lexus and Mercedes have conditioned upscale convertible buyers to expect potent V8s and a smooth ride quality in this price bracket. But like other BMWs, the 645Ci immediately establishes itself as the athlete of its segment. We don't mean to speak for hard-core enthusiasts, who will prefer the Porsche 911 or, as one of our editors suggested, the Maserati Coupe. Rather, the 6 is for those seeking a gifted touring car that eagerly and deftly takes on a twisty road when given the chance, while dutifully swallowing up mile after mile of freeway pavement without complaint. Does this supreme balance of attributes give the BMW an edge over its softer competition? If you like to drive as much as we do, yes.

The view from outside is special and rich, but the view is arguably even better from inside the car. Our Silver Grey test car had a contrasting bordeaux and black interior constructed of top-quality materials under the direction of an exacting hand. 

Even with the presence of the 21st-century iDrive vehicle management system, the 645Ci's cockpit retains a remarkably simple, driver-oriented feel that establishes its place in the BMW family tree (before it branched off to form the current 7 Series). Everything — from the way the human body fits so perfectly into the sport seats to the ease with which you can read the analog gauges to the way the manual transmission's shifter falls so readily to hand — gives the coupe a timeless quality that all the software in the world can't take away.

While other manufacturers have experimented with various ways of illuminating the cabin, BMW continues to stick with bright orange backlighting for the gauges and controls. It's easy on the eyes and establishes an immediate link between a 2004 645Ci and previous BMWs that customers might have owned and loved. There are no roots to trace when it comes to the layout of the automatic climate control system, but this is the simplest setup the company has ever offered. Able to function independently of the iDrive interface, the system features dual temperature dials for the driver and passenger and a real "off" button.

POWERTRAIN- 

The sophisticated 4.4-liter V8 under the hood is a meal by itself. Also found in the 5 and 7 Series lines, this engine is one of the most advanced eight-cylinder motors currently offered in a production vehicle. Continuously variable valve lift (called Valvetronic) eliminates the need for a conventional throttle and, together with infinitely variable valve timing (double VANOS) and a fully variable intake manifold, maximizes power and torque across the rpm band. The result on paper is 325 horsepower and 330 pound-feet of torque. Numbers like these are almost commonplace among luxury vehicles these days, and it's not until you experience the engine for yourself that it seems like something special.

Paired with the optional Steptronic Automatic transmission, the 645Ci moves out quickly, and power builds and builds as the tachometer's needle climbs unwaveringly to redline. Indeed it's potent, going to redline seems like a perfectly natural course of action. A carefully tuned exhaust note assures a glorious soundtrack in these moments of revelry. Even if you're not one to throw your driving record to the wind, you'll still enjoy the effortless passing maneuvers made possible by the V8, not to mention its quiet cruising demeanor.

BMW claims a 5.5-second 0-to-60-mph time for 645s.  We came very close to that in our instrumented testing, as our convertible made the run in 5.6 seconds and breezed through the quarter-mile in 14.2 seconds at 99.5 mph. Fuel mileage ratings are encouraging for a V8-powered vehicle. Cars equipped with the six-speed automatic fare the best with an 18 mpg city/26 mpg highway rating. 

The mostly aluminum 6 Series chassis provides the perfect complement to the excellent drivetrain. Suspension parts are shared with the 5 Series, but the 6 gets a lowered ride height, a slightly wider rear track and greater negative camber in back. The front springs and shock absorbers are firmer than the standard 545i settings but not as taut as the sport suspension calibrations on the manual-shift 545i (an optional sport suspension is not available on the 6). BMW's Active Roll Stabilization (ARS) is standard, and in simple terms, that means that our 645Ci had "active" front and rear anti-roll bars — with distinct left and right sections that twist in opposite directions to suppress body roll when going around corners. Besides improving performance on twisty roads, BMW product literature notes that "there is a psychological component: Drivers and passengers alike marvel at the resulting 'flat cornering.'"

And marvel we did at the 645's handling. After a day on some of our favorite two-lane highways, we came away impressed by the coupe's superb grip and balance in turns of all varieties. High-speed sweepers, tight washes, you name it — the 6 is unflappable. Although the car is too big to impart the extension-of-my-own-body sensation of a 3 Series, it certainly does right by high-dollar coupe buyers. The suspension transmits plenty of information through the driver seat — such that the driver feels like he's in on everything that's happening. At the same time, the ride quality is smooth and refined over all but the roughest pavement. Various Mercedes models may be able to keep up with the 645Ci when it comes to refinement, but not one of them can duplicate its entertainment potential.

Active Steering, a bit of technology that debuted on the 5 Series, is also part of the 645's Sport Package. It differs from the standard variable-assistance steering in that a small electrically controlled gearbox mounted near the bottom of the steering column increases the amount of rotation that occurs when the driver turns the wheel. The idea is basically to reduce the amount of effort the driver has to supply during low- and midspeed maneuvers, and the system is able to take into account vehicle stability and uneven road surfaces, in addition to speed. The extra assistance is gradually reduced as vehicle speed increases, until the ratio becomes "conventional" at about 75 mph, according to BMW.

Although it might sound like BMW has taken a portion of the driving experience out of the hands of the human driver and put it into the algorithms of a computer, Active Steering actually works quite well on the 645Ci. For starters, you don't have to turn the wheel nearly as much in a parking lot. At higher speeds, our test car's steering felt quick, accurate and highly communicative, requiring only subtle inputs in the turns. Of course, this could easily be a description of any BMW's behavior on twisty roads, and lacking a non-Sport 645Ci for a side-by-side comparison, we can't say that Active Steering is an absolute must-have item. It is worth noting, though, that engineers were able to incorporate additional functionality without taking away any of the world-class steering feel that sets BMWs apart from their peers. Editors' descriptions of the 645's steering ranged from "natural" to "nearly perfect."

Braking is easy to overlook when discussing the more glamorous aspects of the vehicle, but like other BMWs, the 6 is near the top of its class in this category as well. Brake pedal feel is straightforward, progressive and considerably more natural in feel than that of Benz models with electronic setups. Braking distances are plenty short in everyday traffic, and the 3,800-pound 645Ci consistently stopped right around 120 feet in the 60-0 deceleration test at the track. This is a good number, of course, but consider that despite its subpar pedal feel, the 4,000-pound SL500 can haul down in an otherworldly 109 feet in the same test.

Back inside the cockpit, the Sport Package provides excellent sport seats that hold you in place during hard cornering without feeling too confining when you're just driving to the grocery store. We spent three hours in the driver seat with no discomfort. There's plenty of room to adjust the seat in all directions; longer-legged drivers will particularly like the manually extendable seat bottom, which provides additional thigh support.

Visibility from the driver seat isn't bad for a convertible or coupe, and all three of the mirrors have an auto-dimming feature.  Ordering the Park Distance Control option should help you avoid any low-speed mishaps, as the front and rear sensors provide both audible warnings and a graphic display on the iDrive screen. Bi-xenon headlights are standard for maximum visibility at night.

All cars with a dramatically curving roofline require those of taller stature to take extra care when getting in, but the 6 demands a little more concentration due to its high lower door sills. The sills can easily trip up an inattentive passenger the first time he gets into the coupe, and anyone with arthritis should check this out during a test-drive before placing an order.

As you'd expect, occupants are well taken care of in the 645Ci in terms of safety. Airbags are standing by to protect everyone's head and torso in the event of a collision, and an advanced stability control system is onboard to help you avoid an accident in the first place. Storage space for cell phones and CDs is surprisingly generous, though, as a large center console container is ready to swallow up most odds and ends.

VEHICLE CONDITION:  The factory finish on this car is glossy and free of major blemishes or imperfections.  The car has been piloted carefully through country roads and highways.  The owners were non-smokers and the vehicle is free of any odors.  The interior is stain free and immaculately clean.  This car has been garage kept and has never been in a material collision.  The rear bumper was refinished due to a minor incident several years ago.  Documentation is available to confirm the minor nature of this refinish work.  The bumper was painted several years ago and to the finest standards by one of the elite shops in the Philadelphia region. There is a minor stress crack at one of the bolts on the right front fender.  This is common since the 6 Series uses a Plastic resin fender to reduce weight.  We can have this repaired, but hesitate to do so since the paint is original and the defect is nearly undetectable.
