Oh, I was only thinking about A/V stuff.
In that case, options I would like to see (on a turbo'd car) are:
- anti-lag
- modifiable fuel injection mapping (so I can make it nice and torque'y or a redline screamer)
- adjustable suspension
- switchable normal/power assissted steering
- adjustable exhaust volume/note
- Straight cut gearbox (except in 5 & 6th!)
- cruise control (my granada has it and it's awesome!)
