My mother drives a 2001 Taurus FFV. She bought it used and it did not cost any more than a standard used one. FFV is a free option from ford on select new cars. The only problem is that almost no one sells ethanol E85, only two stations in all of Virginia. The reliability of FFV's is better than standard gas vehicles if ethanol is used, ethanol burns clean and does not leave behind any carbon build up in the engine. Ethanol also burns better than gas, so there is an estimated 10% improvement in engine power. The ethanol used by FFV's is an 85% ethanol 15% gas mixture.
