NO, no need to pay over sticker unless really desperate for one. MOST dealers are still selling them at cost in my Tri state area, Ohio PA WV. Of course, you still have to catch one of the lot.
On my XLT AWD, I drive about 80% highway and fill up weekly. I avg about 25.5 on the week. A recent 200 mile trip, rolling hills in PA and WV and I was very happy to avg almost 29. I don't see ever doing better unless it is a perfectly flat trek at 65 mph.
When it's say below 30, mine always goes in to the "disabled to save battery life", even if I had just driven it 2 hours earlier. I just have to accept that the "App version is only a feature in writing, not in real life. I park with in a few feet of my home, between my house and big garage...
I'm in Ohio. The App Remote Start ONLY works in warm weather, never when the windows need de-iced. (even is truck was driver a couple hours earlier) I'm now wondering it if will work in HOT weather? Or will that be disabled also?
