The 7 Series is BMW at its finest. This limousine is offered with various engines, ranging from a 315-horsepower 6-cylinder to a 536-horsepower V6, and there's even a diesel. A version with an extended wheelbase is available, as though the regular variant wasn’t roomy enough! As you’d expect, the 7 Series isn’t exactly inexpensive, but when it comes to a palace on wheels like this one, why would you deprive yourself?
