I wanted to add my 2 cents worth to this discussion thread. After doing my research I purchased a Covercraft car cover for both my 240-Z and my Torana in the "Noah" fabric. When the cover for my 240-Z arrived, it had two mirror pockets in it, one on either side where the doors are. I had to send it back as my car has the front fender mounted mirrors...so lesson 1 here in ordering from them is to be VERY specific regarding things like this. One thing which is my fault as I didn't think of it is that the Torana has a exterior black plastic louver on the rear window, no allowance as made for this and hence I am unable to have the louver fitted to the car with the cover on.
Second gripe, the cover damaged the chrome on my bumper. Periodically green oxidation muck would form on the chrome bumper where the cover touched the bumper and I had to continually polish it off; it ended up slightly pitting the fresh chrome on the bumper. I have the bumpers covered in cotton summer weight bedsheets now in several folded layers prior to placing the cover on and it now protects the chrome.
I hope someone out there finds this info useful PRIOR to ordering the Covercraft cover. It is a good cover, but be careful ordering please.
