The BMW M6 launched in 2005, and is powered by a massive 507 horsepower engine and 5.0-liter V10. This engine provides exceptional power that can accelerate from 0 to 100 kmh in less than 5 seconds, although the top speed is limited to 250 kmh.
The running costs aren't cheap, and other engines from the BMW 6-Series offer better fuel economy than the M6. Luckily the car is pretty rare, so resale value still remains high for anyone who takes care of it.
While you shouldn't worry about the reliability of mechanical components, some of the recently introduced electronics can go wrong.
Given the security of the BMW 6-series, protection against thieves is excessive, which is good for the future owners of this automobile. The BMW 6 series has a completely customizable comfort setting with IDrive, which can be set for any member of the family.
There isn't much legroom in the back, and the boot isn't too big either as this is mainly a sports driven car. The interior is luxurious and comes with a bevy of features you won't find in any other cars like this.
There is a huge list of optional components which can be added to the car, but each is rather pricey and will raise the cost considerably. Navigation with voice command, IDrive control and even the Heads-Up tool are available as standard.
