 I have the Sport edition 740iL.  The car is phenomenal.  Unbelievably roomy interior, great styling, and despite its size, it still handles nimbly like a much smaller car.  Easy to understand and well-laid out controls.  The throttle response is very linear and predictable, and it has an amazingly tight turning radius.  It takes a licking and keeps on ticking.  Mine was hit twice in the rear and once in the front (before I bought it), and after being repaired- you couldn't tell. It still handled and drove great.  I love this car.  I bought an S65 Mercedes to replace it, but I still miss the BMW. The Mercedes is a rocket ship, but it doesn't drive as nimbly and instinctively as the BMW.
