How good are loras for automotive these days?

I am a CGI artist, and currently using AI to generate backgrounds for my renders, and add details and realism and then composite them over the renders. Long story short, I never experimented with loras, but I have a client that is requesting a large amount of images in a short amount of time, and I was thinking to train a lora using 3d renders, and then use a 3d render as a base, and use AI with control net on top to generate images.
