Improvements On A Classic Car

For my Charger, I have done the following:
Auto dimming rearview mirror with compass.
Extensive sound deadening.
Classic auto air.
Tremec 5 speed.
Electric trunk latch.
AM/FM/CD/MP3 player.
4 wheel power disc brakes.
Battery in trunk.
Tell me how you like the 5 speed? What gear did you go with?
