If I wanted the sun up there, I would buy a convertible.
I don't like worrying about leaks, seals, the sliders, the mechanism failing etc...
I don't like glass above my head.
I would prefer the roof above me with no hole in it.
The list goes on but no one cares about my list.
Sadly, I was asked.
I want another P10, must be 5 speed and no sunroof and I will buy if it is relatively clean.
