I purchased this vehicle with 9,500 miles on the Odometer. It has been an incredible car. Fast, reliable, comfortable and economical. I drive very aggressive yet still average 23mpg overall in LA's bumper to bumper traffic...amazing mileage! We also own a 06 330xi...also a great car - a lot more nimble than the 5 series when driving twisty roads...but the 545I can easily keep just using the extra power.
Six speed sport transmission...active steering...it's truly a drivers car.
Take the run flat tires and throw them in the trash. Once the car is equipped with regular radials...(it has a spare) it is a new car. Inside noise was reduced by almost 10 decibel pts. from 74 to 63 at 80mph by replace the Bridgestone Potenza RFT. Oh and now my Idrive works using voice command.
