goodness me, what fungal growth you have....
just make it a habit to park your bimmer at least 2x a week in the 1Malaysia matahari
with windows wound 2cm down to prevent microwave efx and ur F-free!
if you sweat a great deal then ride a bicycle to dry off b4 driving ur bimmer...it works!
or else get some promo T-shirts for ur seats to wear for sweat absorption.
other than that if u got LV wallet then send wheels in to Megs for conditioning fortnightly.
Hope my hints can assist, or else Cdrafts on me!
goooooolux.
