2005 BMW 6 Series 645Ci 2dr Convertible (4.4L 8cyl 6M)


Review

Just bought this car this past august. I've seriously have driven the car no more than two weeks. This car is already a nightmare. Gasket leaks and misfiring issues. Should have stuck with Mercedes. BMW dealer can't even pin point the issue. Very poor customer service. BMW of Peabody ma. Stinks. I'm ready to throw in the towel at this point.

2005 BMW 6 Series 645Ci 2dr Convertible (4.4L 8cyl 6M)


Review

Owned a 308, a 365, two Aston Martins, a slab sided Cobra, more MBZs than I can forget and I have to say this is the finest all around automobile I have ever owned. The car is dependable, forgiving and a joy to drive hard and fast. Spent 14k at 90,000 to replace items that had not yet failed but what does it matter since my old chum has never let me down. Am now at 203,000 miles and all is still well.

Review

Reliability is an issue -
right now I need to take the car to the shop to get the engine gaskets replaced, the intermittent PDC failure analyzed, the trunk lock sensor fixed so that I can open it with the remote, the brake fluid flushed, the interior filter replaced, brake pads replaced, etc.

Review

My wife and I feel in love with our 05' BMW 645i conv. when we first picked it up.
We purchased it Jan. 2011 used with only 33,000 miles on it.
It had some years on it but we figured it would get several years of only normal maintenance type services and not need to worry about major mechanical or electric problem because of it's low mileage and series.
After all this is one of BMW's flagship cars.
While the car gets looks of admiration at stop lights the feeling of this wears out quickly when you count how many dollars and time it has spent in a BMW repair shop.
The BMW 645i is like buying a boat - the 2 happiest days of ownership are the day you buy it and the day you get rid of it.


Best Features

This is a beautiful car that turns heads and people are still not use to seeing the new 6 series so it's still very fresh. The top drops nicely and the exceleration is amazing. If you don't mind your car being in the shop 4 months out of the year and have unlimited funds to repair it, it will be a blast to drive the remaining 8 months out of the year.


Worst Features

BMW really needs to improve on the quality of the car. Major oil leaks from the valve cover and upper timing chain cover gaskets, multiple ignition coil failures, valvetronic failure, water pump failure, alternator failure, master brake cylinder failure, SRS control module failure, DVD - Navigation failure, battery issues, electric window issues, transmission issues, and horrible run flat tires. This is completely unacceptable of a expensive, well maintained, and pampered car with less that 63,000 miles on it. It's quality completely sucks the life out of a supposed ultimate driving machine. Steer clear (please enjoy the pun however) of this car.

Review

The finest car I have ever owned. I have had other BMW's, Mercedes, Volvos, 400 HP muscle cars and nothing compares to this car. It is in a class of its own when it comes to BMWs.


Best Features

The adaptive steering and suspension are amazing! I won't have another car without them.


Worst Features

Faster computer for the idrive. Sometimes it is slow to respond when first starting up.
