Yes, I think that's a great find. I have a vin 15xxx one, April '18 build, that was a return/refurb and it was in excellent condition, and has worked out extremely well for me. I presume yours was a showroom, sat and had people sit in it over and over for a year or so, maybe a few test drives, and then was sent back to tesla to get reworked/refurbed, or perhaps just cleaned up at the location it's at, and now you get to buy it basically new. And as has been stated, the LR RWD ones are the stealth econo unicorns - the ones that actually get the 310 mile range. While they're the slowest cars tesla has ever built, they go the farthest (so far).
