I traded 2 in on my 22 Outer Banks; a 1998 Expedition and a 2013 C-Max, both which I bought new. I sort of miss the C-Max for it's fuel mileage , but I love the Bronco - no regrets!
I use Valvoline full synthetic and change the filter every time. "Makeyouloco" recommends changing every 5K miles to guard against the little filters in turbos and cam phasors from plugging up.
I agree with what's being said so far. It seems Ford is more interested in bringing out new models than taking care of their existing, patient customers. In the mean time dealers are selling brand new ones on Bring-a-Trailer! What's wrong with this picture!!!
