The actual city of San Francisco is not representative of the weather in the overall Bay Area. I open my sunroof nearly every day from March/April to September/October.
Agreed--and actually, there is no "overall" bay area weather, since there are so many micro climates. The weather in areas only a few minutes apart (particularly on the peninsula) can be vastly different.
lol..that's where i got my Prius III w/solar. Apparently they are under the same ownership as the one in Marin so the latter was able to make a dealer exchange. They've definitely earned my repeat business
