I am a little worried about the heat (or cold) since my girlfriend will be in the car and she tends to get a bit annoying in the cold.
An additional layer of clothes might help...
as the heater works really well (CUT) Any remedies to the fogged up glass?
Just turn the above heater on.
I never had any trouble and it always demisted the windscreen in no time.
For the side windows, I carry a clean rag.
A girlfriend is useful as she might wipe the passenger's window which is not easy to reach.
