Have done the same today. It's a nice Car and feels bigger inside then the Seal plus to step in and sit in the Car is more comfortable. It is a 800V Battery with 82.5 kwh, so not the bigger one you can get in China or Europe. The price for the Performance AWD is 1.2 M THB, but will go up after the Motorshow to 1.4 M THB and is available sometimes second half of December.
Out of interest I have asked what I would get for my 7 month old Seal Performance. They have made some pictures and copy of the blue Book and send it to a second hand Dealer where they are working with. After 20 minutes waiting I've got a price for my Seal. As response I've just told them if they want to keep me as a customer they should not give me such a answer. Turned around, wished a nice day and left.
