When searching for floor mats for Scott (run.exe) at Blue Ribbon Motoring (dba
www.autoanything.com), I bought a car cover. The salesman (and myself) steared me to the Ultraguard (
http://www.autoanything.com/ultraguardcovers.asp) and I ordered one in gray. It is fabricated in Orange County, CA and it should be here in a week.
I chose the Ultraguard because of it's durability, the thinness (can be washed in a home washing machine) and other factors too. Check out the link. I paid about $280 for it, including tax and shipping. Oh yeah, it's for the 500E.
