I got it into my head that a true hacker must know how to hack his car. Especially the dash. You've got the connection to the car's diagnostic computer, DC power (without occupying a cigarette lighter port), auxiliary audio, and the ability to use any blank switchplates you might find there.
I found that the average hacker can probably figure it out, but with a caveat: you have to use much more force than when building a computer (for example). The car's retaining snaps and bolts were designed to stay in place in a vibrating environment, extreme temperatures, and in the event of an accident. HOWEVER! The force you apply must be at the correct time and place. The same force you use to disengage a connector or snap could end up tearing a tab somewhere if you force it too much. If you feel inordinate resistance, check for screws. Basically, it's the same as disassembling your garden variety coffee pot, but with more prying force and snap tabs. Be careful!
