I have a 7k drive to and from work and spent most of that with my head out the window.It depends on how it is used.
The missus drives hers to work so in winter she has to deal with the frozen/steamed up windows and poor initial heat output etc.
It's just warming up and clearing the windows as she arrives at work!
Where l drive my 110 all day between customers jobs, so once it's warmed up it's OK for the day even if left for an hour or more while l am on a job.
I think the heated screen will be great in her 90, not needed so much in my 110.
7000 miles that's one heck of a drive to work!!!I have a 7k drive to and from work and spent most of that with my head out the window.
