Or mount it in front on a brush guard, using the hood as a ground
plane, aussie style.

I did this with a screwdriver on a VW Passat wagon and it worked
fairly well, RF wise. Terrible from a human factors standpoint
though. You tend to forget its there, until you whack something low
overhead, and, with a screwdriver in particular, you really need to
be able to see it.
Moved it to the front (hooked to one of the tow lugs).. if you look
at my page on qrz.com there's a picture of it there.
But when I went to a new car, without any convenient places to bolt
things in front, I went to the long whip with an autotuner in back
approach. If the new car were an SUV, I would probably go with the
front mount (more active length of antenna above ground plane while
keeping overall height the same)
