I currently own a 2016 Model S 75D, with AP1 hardware. I am at the 45K mark, and my warranty will run out at 50K. So far, no really big issues other than some tail lamp condensation for which they got replaced, and misailgned power windows on the passenger side. If I sell my car now, I can cover the remaining loan and just get into a Model 3 for less than the remaining loan amount while having a car with HW which will last for several more years, and under warranty. Looking further ahead, I see that there will likely be a major refresh of the Model S coming in the fall. I am guess that the value of my S will drop sharply at that point. The S is obviously nicer, but should I switch now and get the maximum value from my S, and also not have to worry about out of warranty repairs (and bills)?
