I am a car nut! I wanted performance and I got it. The 750IL has more than enough juice for any driver right off the line. As I am finding out there are plenty of ways to improve both the performance and the mileage. It does have some quirks. There is a sensor on everything in the car and sometimes they give out reading that are hard to understand. That is what the gear heads at the dealership are for. All in All there are few automobiles that can top the luxury items or the high performance of this incredible machine.
The faster you go the faster the car gets. Top end is the best part! Although 0 to 60 in 6 seconds isn't bad for a 4200 LBS car.
Keep it simple. The new ones almost have too many features.
