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

Cup holder.... it's something we build into most of the cars we work on. Although it's so dam hot in the race car that I dont mind holding a cold bottle of water between my legs...

And a phone charger...

I've toyed with the idea of adding dynamat but I've gone through so much trouble to cut weight out of the car I just can't do it....

Turn signals and headlights maybe......
