Ha, hadnt thought about the rain.
The way I see it is that practicality and ferrari really dont mix well. They're amazing cars, all of them. When they're built for the track they're even better.
Would you buy a $14,000,000 gto if you had the assets and the opportunity? I would, and thats not 'practical'. Neither is driving a 250 gto, it could get damaged, dinged, crashed, wrecked, the miles!!!! So many things that arent very practical.
Not to mention speed. The scaglietti is a 2+2 topping out at 200mph. The top speed on the roads of PA are 65mph. You CAN track a 612 but wouldnt you rather track a CS?
In any case I think the barchetta is amazing for what it is, a design piece. And you better make sure its sunny out or carry a couple towels in the garage just in case!
My two cents.
