What late model accessories do you wish your old car had?

As my dad used to say... " The parts you don't add don't cause you no trouble"

No PS, no PB, no EFI, no electronic ignition, no electric fans, for me.
Edit .. I forgot no AC

KISS principal for me!

Oh I did think of two things... Ear plugs and a blanket... Convertibles can get a bit loud and cold at 75 mph:rolleyes:
