As many posters have already indicated, the choice of 550 vs 535 depends on your priorities. For me, the choice wasn't about $$$ as the extra cost of the V8 vs the inline 6 wasn't the driver of my decision. I balanced the extra power that I would only have rare ocassion to use against the far superior gas mileage which would be an everyday benefit. The 535i is not a slow car by any stretch of the imagination. And the power is effortless. There is no sense the engine is going to hemmorage as one previous poster implied. So, in my opinion, the 535i hits the sweet spot. Drive both, think about it, and then decide. Whatever you decide, you will have no regrets. The f10, 550 or 535 is a great car.
