This is our third Explorer. I just love them. This one has 130,000 miles on it but it run and looks great. I wish I had gotten the V8 this time but only because I tow a trailer. I have put a air bag module on it and a Clutch fan. Other than that and some new tires it always goes.
Big and roomy, goes good in the snow, feels solid and built well.
I think the improvements that I can think of have been addressed with the new design, like lower center of gravity. Better ride. Better MPG (which I doubt they can do much about)
