First of all, it's LoRa. It is based on my favorite Nissan Cedric/Gloria Y31 Hardtop from the years '87-91. It is a test model, so it has defects. I don't remember how many samples and epochs were used in it... But, with some of the checkpoints it turns out very similar and funny.
The best images I was able to get with this LoRa were at these settings:
Steps: 25
Sampler: DPM++ SDE Karras,
CFG scale: 6.5
and with LoRa strength 0.8-1
