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

After reading most of the post there are some pretty cool options that can be added.

Be true to why you have your old car. If your someone trying to "Remember When" Thinking back to what it was like.

I remember clearly getting into my 69 Corronet R/T on a 90 degree day. Manual steering, 4spd., drum brakes,

Once I fired that car up I don't remember any one ever asking. What amenities were available ?

The only thing that I thought it should have was better brakes and tires.
