I have had a nasty habit of trading vehicles all the time myself, rarely putting more than 10-20K miles on them. I do plan on keeping this EcoDiesel for a long time, but we'll see how that goes. Yes, I'm aware last gen EcoD's had some nasty issues. The fact is this engine has been almost entirely re-designed and has only been out for a year, so you assuming it's going to fail is ignorant. Regardless, that's why I have a 8 yr/125K service contract. I won't keep it any longer than that. My point still remains that the used market is important, and vehicles shouldn't be considered so easily disposable. People buy used to save money. Imagine buying a Lightning used in a few years and shortly thereafter getting hit with an outside-of-warranty battery replacement. Ouch. Diesel repairs costs are not the same as gas either, which is what most people are driving. My mom has about 300K miles on her 2009 Aspen with the 5.7 and has had 0 major issues, and barely changes the oil. I don't know if it's a miracle, or an indicator of how well they've nailed down engine production.
You won't be getting a DC fast charger. You won't be getting any charger, actually. The charger lives in the vehicle. What you plug into at the wall is just a means of connecting line power to the built-in charger which then converts AC to DC (this is what you would install in your home). Level 3 DC fast charging (typically anything 20+ kW) does the AC to DC conversion in equipment outside of the vehicle, and then directly juices the battery, bypassing the internal charger.
