First of all:
it´s about your car.
You´re here because you want some protection for your car, in order to preserve it the best way possible,
to keep it clean and in good shape, so it´s ready for use any time you want and keeps its value.
It´s important to keep this in mind during the process of chosing a cover, and not get distracted by trivial things that have no added value to the protection of your car.
Not just your budget or esthetics, but mainly the storage conditions determine
what cover is suitable for your needs, or if you should even consider using a storage system instead.
Climate plays an important role and even if it may be changing, North West European conditions
are still very different from those in California or Southern Spain and require different features
from a cover both indoors and outdoors.
