Aircon is a great asset in an open top car that gets wet, it has certainly been a boon in my smart Roadster which has had it's fair share of dampness, anything you can do to remove moisture from any electronics - even the relatively simply Morgan dash boards will suffer and in humid or damp weather great for keeping the cabin screens clear.
The amount of nay sayers in the smart roady world who say you don't need it (never had it or their's broken) are the type that only take the car out of the garage on dry days.
I guess you can always buy the Guardian to soak up the water that is more in keeping with tradition?
Oh and on really sunny hot days???? A/C is great for cooling ones toes!
