Incredible automobile! The 4.8 liter has smooth power delivery, automatic transmission is good match. Great for commuting, canyon carving, and street races. A real sleeper, can out accelerate nearly any vehicle on the road, and do it with style, while carrying several passengers. Luxury features are fantastic, iDrive very convenient once mastered. Navigation system is excellent. Logic7 sound system is incredible. 20-way seats are extraordinary. This is a real drivers car, 525 and 530 do not even compare. The 550i in different league, very much worth the 20k premium. 0-60 mph in 5 seconds and the quarter mile in 13 seconds, encapsulated in a very luxurious cabin… the only way to travel.
4.8 liter engine, 360hp, can run with the big dogs. Transparent traction/stability control system, iDrive, navigation system, Logic7 sound system, sports seats.
