Hey, It looks like rain here (for once) so I ordered a car cover from pep boys
one of my shopmates has the exact same one already and its super nice quality, waterproof, nice elastic around the edges, and fits over his s13 (with dmax aero) perfectly. covers the aero 100% (if you have a gtwing or larger wing it might not fit as well though, you would need a size D probably
he paid $80 for it, but pep boys has a discount code right now for 25% off

(size C fits an s13 hatch very nicely, they have larger or smaller sizes for other vehicles. I ordered a size c for my 240, and a size e for my y34)
discount code is 25pep and its good till 9/21
