Oooh, a beige K10 :laugh:. I've done that before when I've been pulled over - told them pretty much the same thing and nearly got arrested for it. Cops don't seem to like smart/sarcastic people. They're only wasting their own time. And it was all about the long drives, still is in fact (Y).
And as funkydoody says - just get a decent headunit, some better door speakers, some 6x9s connected to an amp, a sub, and also do a few free cosmetic mods (de-bumpstrip, open-mouth bumper, open-mouth grill, window tints, tinted headlights/siderepeaters/brake lights, remove the rear wiper), and you're good to go (Y)
