You probably are over thinking it....

If you have a fiberglass roof, you can take a piece of sheet metal and glue it to the center and use that as a ground plane. Crude but effective.

Or, check out the various style of antenna mounts available from www.hro.com

You can get a mount that will fasten to the windshield and provide a good ground plane through vehicle body. Those are not mag-mount antennas.
