Re: It's just not the same ...
I agree that with the top up, visibility out of the roadster is limited. But why own one and drive with the top up. In the last three summers it's been top up probably 20 days. It's garaged with the top down (to save on wear and tear) under a car cover. Just back it out, and go for a ride. This October I took it from SW Michigan to NYC in one shot across MI, PA, and NJ, top down all the way and cruising at 80-100 with the radar detector on.
I've had it out at <32o with the windows up and heater blasting.
The wing doesn't so much block visibility as it is a distraction. I just lock mine "up" and ignore it. Besides, why look behind you when you're outrunning everything on the road!
But right now the poor baby is sitting under a couple moving blankets in the corner of the garage waiting for spring.
