I live in Houston and am buying my second Model S. I asked my DES about the possibility of flying to Fremont and picking the car up there, and driving it back to Houston. I was shocked when she told me that if I did that I would have to pay sales tax in both CA and TX! Since I took delivery of my first one in TX I only paid TX sales taxes, and I didn't learn about this as I didn't think of picking it up in CA back then. I am sure she knows what she's talking about, but was also amazed I had not read that on the forum. Has anybody picked up their car in Fremont and driven it home to another state?
