Why do people always go to the 'posers' argument just because someone does something different than them? I love driving my car, but there are times putting the roof down makes no sense, such as if I'm heading to a business meeting and need to keep presentable.
As to temps....well, temp itself is not the deciding factoR alone. It's a combination of temp and sun. A nice clear sunny day? Top usually goes down if temp is in double digits (Celsius).
