We are considering purchasing a low mileage 2019 X Long Range from a private party and wanted to get feedback on what I should look out for. What is the cutoff for the latest "Raven" build, and how can we be sure we have the X rated for 351 miles? We are looking to replace an ICE vehicle that has far more storage then the Y, and it is a little bigger than the X, but range is a big deal with the wife. Any other private party Tesla buyers out there, and anything else I should look for? The only other used vehicle I have purchased was a BMW M3 certified pre-owned, thus allaying much of my angst about buying someone else's car.
