1. Hud on the windshield- I'd like boost and tach on the windshield as well as navi guide. Maybe a light or guide to rev match for those that aren't perfect in 6mt. Something like this:
2. Night vision
3. Built in radar detector
4. Turn off 3 cylinders like the newer accord to save on gas mileage on the highway
5. Ventilated Seats
6. Massage Seats (the one in the volkswagon phaeton were nice.. does 7 series even have this?)
7. dynamic suspension (lowers the front of the car on the highway for better aerodynamics. Mercede's does this)
8. standard heated steering wheel
.... of course some of these will make the 3 series the price of a 7 series... but I would never buy something that big. I like the nimble handling and size of the 3. We can dream right?
