A BMW Boat...

2016 BMW 6 Series 640i 2dr Convertible (3.0L 6cyl Turbo 8A)

I am a big fan of BMW and have had several of their models in the past and still have a 118d in the UK and an X5 from the same year, but I have to say that I was not a fan of this particular car will not be renewing my lease. It accelerates and brakes fantastically and has a surprisingly roomy trunk for weekend trips. There was also plenty of headroom for my 6'1" body and with the 17,000 miles I've had this car there were no issues with it and it was plenty fuel efficient. It'll also do 110 mph on a straight highway all day long and it's quiet for a convertible. But either because of it's enormous weight (over 4,200 pounds) or the fact that it is a convertible and thus not as stiff, no matter what mode the car is in the car is really too wobbly and you feel this from lane changes, slightly twisty roads, and definitely on mountain roads. Because of this, I feel this is more of a highway cruiser than a sports car, I wouldn't even call it sporty. It rolls around like a boat and I hated the way the car felt when the road even got remotely twisty. Another thing that takes away from the sporty DNA I typically associate with BMW is the fact that the it has BMW's fantastic new 8-Speed transmission, but you really have no idea what the engine is doing because you could barely feel or hear the engine. I also had major gripes with the value because besides the LCD dashboard screen, the interior didn't feel any bit as different as the interior of my X5 from the same year, which was much cheaper and has the same engine. The X5 even had a plus on this thing because it had these interior mood lights which made you feel like you were in a nightclub or something. The entertainment was also the same in that the stereo wasn't any better, and there weren't any more features as what I could work out. Overall I thought this car was fast and comfortable on a highway, dependable and efficient, but also too expensive, boring, and the handling is terrible.

Pitch the tires as soon as you get the car.

The car isn't really as bad as I thought. After replacing three tires at different times, all with low milage on them, I decided to try non run-flat tires on the car. This made a world of difference. No more tooth rattling bumps in the road and no more flat tires at over $500.00 per. In all honesty, I bought the car simply cause I liked the looks of it. I overlooked the fact that a car costing $115000.00 didn't have real leather seats, that it rode so rough, or that it was so nose heavy. And, that's exactly what I got : a grossly over priced car that I liked looking at but hated to drive.

It has everything I always wanted in a car. I am car SAVI and the obstacles have been elementary. Not a car for the Novice.

Stylish big coupe

2016 BMW 6 Series 640i 2dr Coupe (3.0L 6cyl Turbo 8A)

This is the kind of large stylish coupe that used to be more popular but is practically extinct now. The luxury elements in this car are great, especially the beautiful leather seats and the sleek body. Great finish and build quality. The 6 cyl is very strong and smooth. Makes for a perfect long distance GT. The problem is this car is very heavy, this means handling while good is not outstanding, and certainly not a nimble sports car feel. The ride is good but the factory run flat tires are poor and not performance oriented (no spare tire either). Very reliable. MPG is OK. The interior is a smaller than you would expect, especially since it is a large coupe. The rear seats are not very usable, but the car does look great in this 2 door coupe form.

BMW's V8 engines are absolute garbage!

Anyone considering one of these cars better do their due diligence on the design flaws with the V8, otherwise you will be in for a terrible ownership experience. This engine is complete garbage and i'm shocked and appalled that a car that cost so much can be so poorly designed and terribly made. I will never buy another BMW ever again. Buyer beware!
