The book answer is the trunk lid on a vert. As long as you center it, it will take no time for you to think thats were it belongs. There are so many cars out there now with them, that you won't even notice it. I do like the idea of putting it under the A pillar cover, just not sure about reception there. A GPS antenna picks up from multiple sats, but radio doesn't. I had thought about just putting mine on the front of the dash. Intend to experiment soon to see how well it picks up there.
