Car Cover
Got mine off Ebay. 5 layer one. Something Armour protection. Do the X1/9 cover search.
What they call semi-custom. Was not that expensive either. Fits nicely, not too sloppy.
I guess the semi-custom is for different car types and no pockets for the mirrors. You could go custom but that will run pretty pricey.
I don't recall the seller, but I think all they do is sell covers.
I use it to cover my x1/9 for extended garage storage.
Got one for my BMW which is parked in the street. Same material (5 layer) works great to keep the elements, such as pollen and rain off the car.
