This is my second BMW. My first was a 3 Series which I also enjoyed. The only reason I traded in my 3 series was due the pressure from my husband to upgrade. Once I drove my 545 just a few times I fell in love. I have never loved a car until I drove this car. I'm a mom and this car was my compromise to Momhood. I have room for three kids in back. Tons of trunk room and a sports car to drive. Yippee. The only bad part is I don't get to play with it very often because I'm usually hauling kids.
This is silly but the cup holders don't fit the car. How many cars can have that as their worst complaint.
This car, while brilliant in performance characteristics, is utterly unreliable. With only 23,000 miles driven, the list of mechanical and electrical problems I have experienced are too numerous to mention. Suffice it to say that this car and the BMW service from the dealer where the car were purchased have provided me with the worst car ownership experience I have ever had. Although born in Germany, I will never purchase another German made car - Japanese cars are simply far superior - an imperceptible loss in performance is worth the peace of mind of knowing you own a reliable, well built machine.
Engineer this car to be reliable. Outsource all of the electronics in the car to the Japanese.
