The Bonneville's not like your BMW at all, but you knew that!
Carb or EFI? My carbed '03 pulls like a draft horse, and I've never needed to even touch the carbs.
The Bonneville is a really nice 3-4 hour ride. After that I want OFF, mostly because of the terrible stock seat and utter lack of protection from wind blast. Guys will tell you that they ride their Bonneville from coast to coast, but this is rare indeed. It's a great bike for for commuting and day trips, and it has good, predictable handling that inspires confidence. At about 450 pounds, it's no lightweight, but it handles like one because of its low seat height and center of gravity.
For me to keep one motorcycle for almost 10 years is something that's never happened before, but this one scratches all of the itches. It does everything well, and has that classic look to boot.
Mine's been completely trouble free except for a slightly leaky fork seal early on. I was advised to wait until the bike had 5,000 miles on it before I ever even considered fixing the problem. Sure enough, at exactly 5,000 miles on the odometer, the weeping stopped and the fork seals have been perfect since.
