Congrats on the ride !! Welcome to the forum. I've got a 2005 and absolutely LOVE mine.
As for the top issue there really haven't been many posting about mechanical "parts" - the most common reports are issues - as FP speaks of - are the window / top
separation where the back window starts to fall out. I live in Alabama and I haven't had any issues with mine. I'm the second owner and the first owner also lived in Georgia...both south states.
But, Enjoy the ride.....it's a blast to drive....personally my preference is TOP DOWN
