Here's a test drive video of my 1999 BMW E39 520i. I shot this video at night for 2 reasons. 1. I wanted to show off the beautiful orange lighting throughout the cabin. 2. The roads are much quieter and it's easier to hear how quiet this car is. I measured this car with a decibel meter at around 60 KPH and it measured 62 decibels, while a 94 E38 730i measured 59 decibels at the same speed. Extremely quiet, smooth, and comfortable car for long journeys.
