Heated side mirrors - Going to install some from a gen 2 W126 and wire them to the defroster switch.

Bundts that don't collect every micron of brake dust.

A PBU that does not spit buttons at me.

A PBU and Becker with real working lights.

A front and rear light that comes on when the front door is opened so I don't get raped by the guy hiding in the back seat.

Better speakers with a small bass speaker.

Longer chassis with fold down rear tables like in a Rolls, etc.

Seat switches that have wires NOT soldered to the damn switch.

Euro adjustable head lights with wipers.

Limited slip / locking diff

2.88 gearing

Over drive
