It's a bit odd to call LoRA representing the car a Skoda 120 Delorean. But whatever.
The infamous Skoda 120 was the most widely used car in communist Czechoslovakia in the 1980s. It was even common to wait several months on the waiting list for this miserable product of socialist planning! (Unless you had the necessary friends.)
LoRA runs on automatic. Just type in a prompt that includes the car, the environment, and the lighting. Nothing complicated.
Trigger words as such are not needed. But there are two essential ones. What annoys me is that in pictures that show a moving car with a blurred background, the car always has wheels that don't reflect the motion blur. For this reason, LoRA knows two terms: use 'spinning wheel' in motion pictures and 'still wheel' for static pictures.
Strength: 1, cfg: 4, sampler as you wish (look at the pictures, it works with anything).
Enjoy.
