I know what was promised but what milage would you be willing to accept and why? Would less than promised be to get higher power? Get your Elio quicker? Or at all? I would probably be happy if it got 45-50 mpg if it meant I would actually get one. I had a Geo Metro 3 cylinder stick shift I purchased new and the wife and I had a contest to see who got the best highway milage. She won at 51 but I was a close second at 49. I would be Ok with that in an Elio IF I could actually get one! What say you?
