I drove all winter in NYC and my 200i never failed to start, not once, with temps. as low as 0 degrees Fahrenheit. I did make a point to take it out for a mile or two, every 3-5 days when it was the coldest, but drove regularly (about 20mi a day) once the temps. hit 15- 20F. Also I occasionally add a fuel injector cleaner, once or twice a month, just a cap or two. As a daily commuter I often enough run the tank to the first, or more uncomfortably, to the second red line of the gas gauge, (there are just very few gas stations left in Manhattan anymore) and I have yet to have any problems, other then anxiety as a result.
