I have covers for all my cars but the Odyssey does pose a little bit of a problem - that blasted fixed antenna! The manufacturers say you should put a hole in the cover for the fixed antenna but I would rather they had a retractable one. My tip - just make sure the fabric is breathable. Mine use the Evolution 4 fabric made by Kimberly-Clark.
Thanks! Do you know if this is something I'll have to purchase online or of any stores that carry them in a size that will fit? I've been trying to find one locally but haven't come across any the right size yet.
What I do to buy accessories is to look in the back of a car magazine like Car & Driver and call several of the shops that sell car covers - get them to compete with each other on price. Generally you will get a price that will be hard to beat except on a group buy.
