With the heater on,I don't think you will really be that cold.Wind (and rain) pretty much blow right over you.I used to drive my car with the top down in the winter in N.Ca. with temps in the 40's and was never aware of being cold.Dress like you would for winter outdoor sports such as sking or cycling, with a wicking base layer to keep your skin dry,jersey,polartec vest and a windproof light jacket with ventilation in back or under arms.And of course a wool beanie!The car sounds outstanding-titanium,in my opinion is SPF's best color.Don't think you will ever get tired of looking at that combo.
