I bought a 7 series thinking it would be very reliable by price/bmw rep. While the car looks nice and is fun to drive it has had so many problems. I have had fault lights going off monthly, there is a problem with the moonroof whistling - BMW states this is common for their cars, my speakers on the logic 7 crackled for 10 months before they could locate the problem (at least 5 visits to the dealer) and my tires went bald at 16,000 miles and cost $700 to replace. This is not anywhere near the relaibility, function, performance one would expect form an $80,000 car. I had less problems with used cars in the 80's. 15 trips to the service dept in 16 months has been inconvenient to say the least.
Interior upgrades, iDrive, hands free controls
Manual for all of the voice prompts that exist. Better reliability. Fix the moonroof whistling problem that apparently has plagued this car since the early 2000's.
