Well, if ya can't keep'em out, at least try to make it hard for them to pop the ignition - I have something called "armored ignition" on mine. Ya gotta get into the column, then place this solid steel box around the entire ignition assembly. It has break-off bolts for installation, so if it ever needs to come out, it will be by drill. It's pretty thick stuff, and it completely encloses the lock cylinder, so it can't be popped out, much less pried apart.
I also have a little steel box that is attached under the center console. It's the perfect size for the ol' Glockamolie, spare mag, badge and a set of cuffs. It's electrically actuated, so in an emergency, one touch of the hidden button and the contents are in your hand! I never worry about someone breaking in putting another stolen firearm on the streets. It also has an additional key lock for added security if you feel like it's needed. (Of course I use that on the very rare occassion I have to leave the truck with the dealer in case someone accidently "bumps" the button. ) It's not as large as Geno's but it's a damned sight more convenient if you need to grab something in a hurry.
