CarJacket vehicle storage bag. Your car comes out as clean as it went in. Keeps out dust, rodents, flash rust. Cover the car with a soft cover or blanket and place some dessicant inside the bag before zipping up for storage. The zipper pulled loose on this bag and I took it to CoverCraft and had a new zipper put in it, now it works better than new. Here's a link to the manufacturers website:
Carbag.com This bag is size M2 (cars up to 210" long) that sells new for $250. I used it for 66-67 Chevelles and 70 Buick GSX and 70 Chevelle and they all fit fine.
$125 shipped in the lower 48.
