We've sold four Teslas online. For three of them, the buyers flew out to Colorado and drove back to Nevada, Michigan and Minnesota, respectively. For the fourth one, we drove it out to Nevada and flew back.
If I were buying a used one online, I think I would prefer to fly out and drive back vs. having it shipped. If buying new inventory from Tesla, it could work either way. We actually tried this last week and had plans on picking it up in another state. Plans changed and then they ended up shipping it. There were some logistical issues so we didn't get it on Saturday but will be picking it up today.
