I have a Coverking Satin Stretch indoor car cover for sale...
This fit my 2003 Boxster S perfectly... I suspect it will work for any 986.
Example here:
Coverking Satin Stretch Car Cover, Coverking Satin Covers
Only used about a year... I think there is some smudge on the inside back right area where I had put it on after cleaning my car and some of the tire clean got there, but that is long dry and really the entire cover itself is clean and like new other than some wrinkling from being in the storage bag.
This cover is NOT water proof but is indoor and breathable. I have the original stuff-it bag it gets stored in as well. Color is Gray/silver.
New it lists for $400 and sells for $270. Asking $125 plus shipping. I also have a red clip I will throw in as well. I am in Northern CA.
thx
