Have you driven a 740? They're fast. I test drove one when I had my E93 M3, and I was pleasantly surprised. It felt faster than it had a right to, and I think anything up to 60mph and both 7 series cars will be relatively similar in performance. One thing about the 750 I don't like - slow throttle response. Not sure if that afflicts the 740 - may be worth a try. In San Francisco, I doubt you'll ever feel you need a 750.
