How do they change the repair process?

The manufacturing process involves building the car from scratch at the factory. They won't change that. However, they will update the repair process. For example, in CCC or the manufacturer's OEM, they'll change how parts are repaired. This makes it easier for the next repair. They constantly update the repair process, but not the manufacturing process.

So whether it's an ICE vehicle or an EV, for minor damage, you will always use a two-post lift?

But here's the issue with all these new EVs. There are so many sensors on the car; sensors for lighting, for other cars ahead, for pedestrians. There are so many sensors that if you just use the basic two post, you might not find all the problems. With EVs, you need to go into full detail, which is why it costs more. There are more labor hours involved and much more information to check. For example, if you're checking an older BMW, you might just need to replace the bumper. But my 2003 BMW didn't have all the technology that exists now, especially on EVs with sensors in the mirrors, front bumper, rear bumper, and all the cameras. That's why it's more expensive for EVs; there are so many more things to check besides just a bumper. If you hit the front or rear bumper, there's also a camera back there.
