You really can't go wrong with white on the G70, great choice and congrats on the new ride!I posted a full thread with pics in the general and wheels and tires sections.
I try to drive it to work once or twice a week and my commute is about 50 miles one way all freeway. I usually have it in normal mode on the freeway and I average about 28 mpgs at an average of 75 mph.
I have 3,000 miles on the odo currently. Purchased in May.
