There have been some - I grabbed one. Had been mainly looking at Model S, and one disappeared literally as I told my OA to grab it ... and then I switched gears a bit for a variety of reasons and found a loaded P90D Model X (Signature) that had about 5K miles on it and a hefty discount. Since I'm doing a 2 year lease on it I wasn't that concerned with the fact that it was an early build... Looking forward to it!
Same happened to us for a white Model S, it was available we pulled numbers up, then it was gone. I didn't jump into an X though considered it but don't need it and don't want to pay that much.
Still thinking I am going to wait for some CPOs and just buy outright unless something crazy pops before Monday and is local, that way I don't need to worry about mileage and can sell the car at any point. The two year leases were nice, just never leased a car and I know the primary point with me and the Tesla was going to be long road trips but I think we would still be able to stay under 10k miles. Two P85Ds on Tesla's site right now, one is priced a bit high IMO for having 41k miles.
