Small sample size on this forum. I too have been a CR subscriber and have been for years. I also participate in their annual products reviews. I bought my GT pre-owned from a non Ford/Lincoln dealership and have had 0 problems. First completely American car I have owned and have no complaints. Love the look, the features, the power, and the MPG for a vehicle of this size. The EV and hybrid driving aspect of the vehicle helps with that MPG. I am not a heavy footed driver, but not a hyper-miler either. I keep the vehicle fully charged for my around the town driving. When the charge is out, I still have the hybrid/gas to fall back on. So again, MPG is way better than it would be if it was a straight ICE.
Sorry for going off topic. Bottom line, do your homework and drive both the reserve and GT to before you make a decision. Good Luck!!
