I see there warranty is four years. I got mine from Griots Garage, it has a Lifetime warranty. Mine was torn and showing it's age and I sent it back about 6 months ago and recieved a new one, FREE! My cover is NOT a "Cobra" cover, they sent a Mustang cover. It's WAY BIG but what the heck, it works OK and I stuff the 'left overs' in the trunk. You can order a Cobra cover from Griots but first they send you a really complicated diagram with a ton of measurments to fill out. Looked like a pain in the butt filling out the form, so I'm happy with my Mustang cover...
Oh by the way, I promptly scorched the first cover on the side pipes! Now I wait for the car to cool down before covering it.
