Last car show I went to with the roadster, it rained all day. Driving em without a top is one thing - most of the water stays out as long as you're moving. No top, leave the car out in the rain and you get to drive home on soggy seats. Warmer too in a cold rain on a bit of a trip. Warmer as well when it's not raining. I do wear a knit cap, hooded parka, sweatshirt underneath etc., but no matter what you do in winter it's gonna be chilly in a roadster. Times like that I turn on the heater. When you have a top, you have the option of running it or not. Takes about five minutes to remove mine and store it away....
