My mother is interested in trading in her 98 Z34 Monte Carlo for a new Ford Five Hundred sedan. It seems like a nice car and has a wonderful amount of room and comfort inside. I was wondering about the reliability and reputation of the 3.0L DOHC Duratec V6 and CVT 6 speed Auto tranny? Please discuss opinions or what your experiences have been with this motor and tranny. Thanks Guys!
