She isn't the least expensive car to own, but she's worth the price. If you love driving, the flagship 7 Series is a dream. Sure afoot, "broad-shoulder" powerful, smooth, quiet, and regal. This is before Bangle. No iDrive either! 14-speaker sound and top quality materials everywhere you look. It always feels like it could be driven across the country with ease. Only 10% of BMWs are 7 Series so you don't see them everywhere when you're driving. Very advanced tech for a 1998 car. Most 2006s still can't compare. Change oil often, replace radiator, treat her nice and she will make you happy.
Rich leather, real wood, clever lighting, handles like a smaller car, beats WRX STIs (I've done it). 20 mpg. Utterly delightful to view and to drive. Best interior in its class even today. No gimmicks. You'll wonder why you waited so long to get one. You'll always volunteer to be the driver.
Better quality radiator (most leak by 100,000 miles - replacement is $600.00 incl. labor), it could use a more sturdy parking brake release handle (mine snapped off at 75,000 miles), less brake dust, and simplify the graphic equalizer (I've just left it at the last owner's settings.)
