I can echo what umamahesh said. This wasn't a smarmy dealer who happened to get a single Tesla and was trying to unload it. These folks very clearly know Teslas and specialize in selling them. In fact, I didn't see any vehicle except Teslas in their expansive, indoor facility. According to the gentleman with whom I spoke, they get a lot of trade-ins and lease returns directly from Tesla. This makes perfect sense to me because Tesla can't sell to the public in Texas. If they get a lease return or a trade-in in Texas, it seems obvious that they would rather sell it to a dealer here than to first ship it out of Texas in order to sell it.
When I visited to look at the S on behalf of umamahesh, the folks there were friendly, accommodating, and absolutely zero pressure.
Having heard all the horror stories online about buying a CPO from Tesla, I think I would rather buy from these guys if I was interested in a used Tesla. Now that I know they're there, I'll put them on the top of my list to recommend as a source for used Teslas in north Texas.
And, umam, I'm glad you got a Tesla. You're going to love it.
