Greetings Model Xers! I am an early adopter Model 3 owner. 18 months old and 56k miles. Love to drive it. My wife and I have made a steady move towards leaving a smaller carbon footprint. We installed solar panels late last year and now we're looking to dump her gas car and replace it with an EV. I love smaller vehicles and she loves something more substantial in size. I originally thought the X was way out of my league but I've seen some Model Xs hitting below the $50k mark. I don't want to go too small as far as battery is concerned and I want dual motors. I was heartened to see a 60D for sale recently under $50k and the owner said it could be software unlocked to 75. However, I'm seeing on the forums that Tesla has stopped doing this. If this is the case, I'll have to buy a 75D or 90D. My long path to the point - Is there any reason for concern about buying a 2016 model? More problems with this year than others? What advice as far as what should I really keep my eye open for in regard to possible trouble down the road? Keep in mind that I am looking outside of Tesla's website (no warranty) as well as inside of it while shopping. Thanks in advance!
