Griot's Garage, got all kinds, some are VERY expensive! Lifetime guarentee, buy it ONCE! I'm getting a new one from them this week, mine is over two years old and showing it's age. They will repair or replace as needed. I put my old one in a box, left it just outside the front door marked: "UPS Pickup". UPS ships it back to Griot's and they ship a new one (or repaired one) back to you!
HOW EVER, they don't have the specifications for a COBRA in their listings. To get a perfect fit you need to ask for the 'measurment' kit (they will send it to you), take the measurments and send THAT back for your first order. EACH cover is custom made. BIG hassle, long wait, cost a lot, but worth all the trouble for me.
I got the 'All Weather' because it's light weight, comes off quickly and stores in the trunk, about $300.
UPDATE:
Calif Car Covers get THERE covers from the SAME manufacturer as Griot's Garage. UNLESS Calif Car Covers has the CORRECT template for a COBRA you will have a problem getting one that FITS! Griots does NOT have an 'item number' for a Shelby Cobra. The first one they sent me was for a SHELBY MUSTANG. I just called them and asked for them to e-mail me their home user 'template' kit instructions. Measure from the headlights to the front wheel, top of the windshield, point A to point B, etc, etc. ONCE we get THAT data nailed down (and I will post it here somewhere) then getting a cover that FITS should be much easier than what I went through. Regardless of WHO you order it from.
Finishline DOES have correct covers, but their selection is limited to indoor use only (dust covers).
If Calif Car Cover fits a C.R., then it aint the RIGHT cover for a COBRA built to original specs! It should fit like a glove, a C.R. is to big...
If it don't fit, you must acquit.
