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

I'm working on suspension, tires, brakes they aren't too bad in their current state. EFI would be nice only because the ambient air changes so much in my area, as well as elevation. Already have a decent sound system.

What I really want is cruise control, cupholders, and INSULATION... wind noise and exhaust cruising at 80 MPH in an old A-body is pretty draining. A/C would be nice but those factory "crotch vents" get the job done as long as I'm not stuck in slow traffic lol.

Oh yeah and overdrive so I can swap in 3.55 gears and still cruise at 80.

ABS for the rear wheels only because those self-energizing drums like to lock up if you mash the pedal too quickly. I really don't like driving cars with ABS on slippery roads, it feels like it barely works and I always end up threshold-braking anyway especially if the front wheels are losing traction going into a turn.
