[Unique427]

Have the California Car Covers "Plushweave" cotton flannel. ($280)
It's a custom fit specific for the Cobra.
Website has drop down menu selection for 289, 427, single/double roll hoop, etc.
Generous cut with elastic bottom.
Very soft lining yet sturdy to prevent door dings and bumps.
I can confirm it holds shape after machine wash.
Can handle direct outdoor sunlight and heat when you need to roll out to clean garage.

The "Supremeweave" is essential the same thing but can handle all-weather for the upcharge.
