Greg,
We traded in the V8 Explorer for a new Impala 3.5 that does the E85. Only Gas City stations carry it in the Chicago area. They need some competition! From what I gather, Minnesota is getting into it in a big way as well.
The Impala was a surprise for me:more than doubled our fuel economy,roomy,comfortable,adequate power from variable valve timing and a lot of aluminum understructure.
