I'd remove weight if there were anything in it I don't like, but the aircon, back seat, stereo, roof liner etc all make it so much nicer when I'm driving it in the hills on the weekends.
Also keeps the cops off my back. I'd say a very legal appearance is the secret for having your cake and eating it.
A sick car stuck on the trailer in the back yard for the weekends the tracks are closed would suck man...
