My answers generally as above with my extra comments being
1 have not had an issue if set to max cold in traffic
2 both only average if you do a lot of country driving change to hid bulbs, low beam easy high a pain in the....( need special mounting blocks i got mine from south africa)
3 an absolute hoot on gravel
4 as above
5 a full size spare will mean the boot mat will not fit properly as the wheel/tyre will be higher than the surrounding floor
6 10% is alowable US cars use a different engine management and so pay no attention to what they do, watch what UK and europe do
7 again the US have completely different head unit and display which has not been used outside of north america so i would not expect any major change here

Hope this helps
