well a hardtop convertible still regains some of its chassis
rigidity once the top is closed.
so i would go for a hardtop convertible if i had to.
but honestly, i prefer a coupe la.
comparing a hardtop to soft top,
soft tops have less complicated mechanisms, hence easier to
manufacture, easier to maintain and less likely to
malfunction.
but for soft tops, there have been cases where vandals have used
lighted cigarettes to burn a hole in it. Once thats done, u have to
replace the entire canvas, which is not cheap. anyone with a
penknife or cigarette or lighter can easily cost u more money than
they can against someone with a hardtop.
hardtop mechanisms, besides being more complex, are also heavier,
but surprisingly, the way they fold out of the way is quite
innovative, so that the loss of boot space between soft tops and
hard tops is quite negligible.
windnoise in a soft top is louder, and because a soft top creates
more friction against the airflow, AND is more likely to get ripped
off by wind lift, its top speed should be affected more,
disregarding the differences in power and weight.
