I am currently driving 5 series 06 model & it is an absolute joy & delight to drive. It is indeed the Ultimate Driving Machine. Here is my dilemma: One month after I got the car, I got a Check Control Message & the IDrive indicated "High Battery Drain!" As per the dealer, I need to drive the car more often because the car has a lot of power & it not good to keep it parked for a long time. I was driving it twice a week & still got the message. I called the dealer again took it twice to the dealer in less than a week. Conclusion: There is a software problem that makes this message pop up & the problem is being worked on in their main office in New Jersey.
Everything is great about this car especially its sleek exterior design, luxury interior, great sound system, smooth drive, quite & powerful engine, & back side is roomy.
More strategically located & attractive cup holders & Navigation system becomes standard on all 5 Series
