Sounds to me like a crap dealer if they don't take this seriously.

Let me support all the messages responding here. When I got my FEH 08, I was so thrilled with how it drove that the great MPG felt like a secondary benefit to me. The big payoff is to be able to sit out traffic delays or go through parking lots with no engine vibration or noise (or cost). Your car should feel better to drive than other cars, not worse and not "compromised."
