I don't know what E85 does to the air outside the car, but I remember when I ran it in my Tahoe the cabin smelled like someone spilled a bottle or three of rubbing alcohol. I always wondered what would happen if I got stopped by a cop.
I'd like to buy a full-size pickup truck, but I'm waiting for the light-duty diesels to come out in a year or so. I am a Chevy guy (one of the first cars I was allowed to drive was the family beater Chevette, and a love affair was born
), but if Ford beats 'em to the punch, I might just have to pinch my nose and jump into one.
