I can't believe it took the aftermarket over 2 years to release these. All that is left now are the ones on the rear bumper and door (good luck with that one).
JDM does not automatically equal reliability. There are a number of trash cars that came from overseas.
Now if you want to switch the topic over to long term reliability on the J29, the jury is still out.
Can be yours for the low price of $300k.

I'm assuming you are talking about the blue and yellow one? From what I understand those two are hand built pre-production cars and not everything works on them. I also wouldn't be surprised if the final tuning and calibration are set.
If we turn back time it was about 6 months after the J29's...
That's because Toyota has stopped production on the 1st gen and not to mention that it is old as dirt/at the end of its life cycle.
A quick reminder of full picture.
