I see this is kind of an old thread.
I just recently went through the car buying experience and was in "EXTREME CAR RESEARCH" mode....when I finally figured out that a PHEV was what I wanted, I had it narrowed down to about 3-4 vehicle contenders, but the Niro and the C-Max were really my top two contenders.
It was the rumors of the C-Max being discontinued that made me take it "out of the running". It was a nice car, but I don't want to be paying through the nose for parts in 5 years if it comes to that. I would like a car is doing well and will be on the market for a while so that parts are readily available.
